Triangles triangle ABC and triangle DEF are similar. Find the angles of these triangles if Mesurements of angle A=100 degrees, and mesurments of angle B=30 degrees.

Answers

Answer 1

Answer:

<D = 100

<E =30

<F =50

Step-by-step explanation

Given that triangles triangle ABC and triangle DEF are similar, this means that their angles are congruent i.e

<A = <D

<B = <E

<C = <F

Given

<A = 100 then <D = 100

<B = 30°, then <E = 30°

To get <F, we will use the expression

<D+<E+<F = 180 (sum of angles in a triangle is 180°)

100+30+<F = 180

130+<F = 180

<F = 180-130

<F = 50°

Hence the measure of <F is 50°

Answers

Answer:

156

Step-by-step explanation:

Answers

the last one is the answer

The measurement of ∠ CSK = 110.2°

What is Parallel line?

Parallel lines are those lines that are equidistant from each other and never meet, no matter how much they may be extended in either directions.

Given that Lines AB, CD, and LK intersects at R and S respectively,

m∠LRB = (3x - 2)° and m∠RSC = (2x - 5)

m∠LRB = m∠CSK  → (Alternate exterior angles)

m∠CSK + m∠RSC = 180°  → (Linear pair angles)

Therefore, m∠LRB + m∠RSC = 180°

(3x - 2)° + (2x - 5) =  180°

5x - 7 = 180°

5x = 187°

x = 37.4°

So, m∠CSK =  (3x - 2)°

(3x - 2)° = 3*37.4 - 2

m∠CSK = 110.2°

Hence, The measurement of ∠ CSK = 110.2°

1.6-metre tall man stands 11 m from the base of a tree. He views the top of the tree at an
angle of elevation of 58°. How tall is the tree?

Answers

Answer:

17.60m

Step-by-step explanation

The set up is a right angled triangle

Given

angle of elevation = 58°

Distance of the man from the tree = adjacent = 11m

Required

Height of the tree h (Opposite)

Using the TOA identity

tan theta = opposite/adjacent

tan 58 = h/11

h = 11tan58

h = 11(1.6)

h = 17.60

Hence the tree is 17.60m tall
