The measure of two consecutive angles of a parallelogram are in the ration of 7:5. What is the measure of the obtuse angle of the parallelogram.
Consecutive angles in a parallelogram are supplementary angles which when added together equal 180 degrees.
The ratio is 7:5 so we would have:
7x + 5x = 180
Simplify:
12x = 180
Divide both sides by 12:
X = 15
So one angle is 7 x 15 = 105 degrees
The other angle is 5 x 15 = 75 degrees
An obtuse angle is an angle greater than 90 degrees.
The obtuse angle would be 105 degrees.

Quadrilateral ABCD is inscribed In a circle.
What is the measure of angle A?
Answer:
[tex] m\angle A = 133\degree [/tex]
Step-by-step explanation:
Quadrilateral ABCD is inscribed In a circle.
So, ABCD is a cyclic Quadrilateral.
Opposite angles of a cyclic quadrilateral are supplementary.
Therefore,
(4x + 5)° + (x + 15)° = 180°
(4x + 5 + x + 15)° = 180°
(5x + 20)° = 180°
5x + 20 = 180
5x = 180 - 20
5x = 160
x = 160/5
x = 32
[tex] m\angle A = (4x + 5)\degree [/tex]
[tex] m\angle A = (4\times 32+ 5)\degree [/tex]
[tex] m\angle A = (128+ 5)\degree [/tex]
[tex] m\angle A = 133\degree [/tex]
Joey had 26 game cards. His friend Richard gave him some more, and now Joey has 100 cards. How many cards did Richard give to Joey?
Given:
Joey had 26 game cards.
His friend Richard gave him some more, and now Joey has 100 cards.
To find:
How many cards did Richard give to Joey?
Solution:
Let x be the number of cards that Richard give to Joey.
Joey had 26 game cards.
Now, the total cards joey has [tex]=26+x[/tex]
Joey has total 100 cards.
[tex]26+x=100[/tex]
[tex]x=100-26[/tex]
[tex]x=74[/tex]
Therefore, Richard gave him 74 cards.
Any help is greatly appreciated!
Answer:
Equation of the line in point-slope form: y - 5 = -⅚(x - 2)
Equation of the line in slope-intercept form: y = -⅚x + 20/3
Step-by-step explanation:
Equation of a line can be expressed in the point-slope form as y - b = m(x - a), where,
m = slope = -⅚
a = 2
b = 5
Substitute the values into y - b = m(x - a):
y - 5 = -⅚(x - 2) => point-slope form.
We can rewrite this in the slope-intercept form, such as:
Multiply both sides by 6
6(y - 5) = -5(x - 2)
6y - 30 = -5x + 10
6y - 30 + 30 = -5x + 10 + 30
6y = -5x + 40
Divide both sides by 6
y = -5x/6 + 40/6
y = -⅚x + 20/3

Draw the following triangle after a 90° clockwise rotation about the origin.
Answer:
Its gonna be in the same spot but just on the left
Step-by-step explanation:
The graph is attached with the solution
What is rotation?Each point in a figure is transformed into a rotation by rotating it a specific amount of degrees around another point.
The coordinates of the vertices of the given triangle are (3,-2), (1,-5), and (5,-4).
The coordinate rule for 90° clockwise rotation about the origin is:
(x,y)→(y,-x)
Therefore, the vertices of the triangle are transformed as follows:
(3,-2) → (-2, -3)
(1,-5) → (-5,-1)
(5,-4) → (-4,-5)
Now, plot the image points (-2,-3), (-5,-1), and (-4,-5) and connect them to draw the required triangle.
The graph is attached with the solution.

a+148=180(Angles on a straight line equals180)
▪a=180-148=32
Now,
a+b=90(A right angle is equal to 90)
So,
▪b=90-a=90-32=58
Then,
b=b(base of iscoceles angles of traingle)
Now,
b+b+x=180(sum of angles of triangle equals 180)
or,58+58+x=180
or,x=180-116

d = √[(x₂-x₁)²+(y₂-y₁)²]...........................
Given: x₂ = -9, x₁ = 15, y₂ = 7, y₁ = 7
Substitute these values into equation 1
d = √[(-9-15)²+(7-7)²]
d = √[(-24)²+(0)²]
d = √576
d = 24 unit.
