(ii) Explain why a+b+c= 235°
This is a cornet maths question. How do I solve it
Answer:
Where is the image?
Step-by-step explanation:
Tell me in comments
The equation a + b + c = 235 is true because a = c = 55° and b = 125°
How to prove that a + b + c = 235?The angle a and 125° are on the same straight line.
So, we have:
a + 125° = 180°
Subtract 125 from both sides
a = 55°
The angle b and 125° are vertical angles
So, we have:
b = 125°
The angle a and angle a are vertical angles
So, we have:
c = a
This gives
c = 55°
Add the three angles
a + b + c = 55° + 125° + 55°
Evaluate the sum
a + b + c = 235°
Hence, it is true that a + b + c = 235°

can someone please help me with how to find the perimeter and area of this
Answer:
Perimeter = 68ft
Area = 289ft²
Step-by-step explanation:
The lines on each side mean that they are all the same length - this shape is a square.
To find the perimeter, do 17 + 17 + 17 + 17 or 17 × 4. This gives you 68ft.
To find the area, you multiply the length and width → 17 × 17 = 289ft²

Which angle in the isosceles triangles is the biggest?
Answer:
Since the two base angles are congruent (same measure), they are each 70°. If we are given a base angle of say 45°, we know the base angles are congruent (same measure) and the interior angles of any triangle always add to 180°.
Answer:

Answer: y = -1/2x + 1
on a shopping trip, Gina buys two books priced $4.99 and $12.99. She also buys 2 notebooks, 2 packs of pencils, and 3 composition books. The books are on sale for 10% off the list price and school supplies are 15% off. The store charges 6.5% sales tax. Item Cost ($) Notebooks 2.88 Composition Books 0.79 Pencil Packs 1.89
The total cost of items Gina bought on her shopping trip given the percentage discount is $26.31
Given:
cost of two books = $4.99 + $12.99
= $17.98
Amount paid for books = $17.98 - 10% of $17.98
= 17.98 - 0.1 × 17.98
= 17.98 - 1.798
= $16.182
Cost of notebooks = quantity × price
= 2 × $2.88
= $5.76
cost of composition books = quantity × price
= 3 × $0.79
= $2.37
cost of pencil packs = quantity × price
= 2 × $1.89
= $3.78
Total cost = $5.76 + $2.37 + $3.78
= $11.91
Amount paid for school supplies = $11.91 - 15% of $11.91
= 11.91 - 0.15 × 11.91
= 11.91 - 1.7865
= $10.1235
Therefore,
total cost of all items Gina bought = $16.182 + $10.1235
= $26.3055
Approximately, $26.31
