Dennis_Churaev [7]

Answer:

option a is the correct answer; ∠A = 68°, ∠B = 22°, AB = 2.9 cm

Step-by-step explanation:

From my understanding, we have to find angle A, angle B and side AB.

Step 1: Find side AB

AB can be solved through the Pythagoras theorem.

c² = a² + b²

c² = 2.7² + 1.1²

c² = 8.5

c = √8.5

c = 2.9 cm

Step 2: Find angle A

Angle A can be found through tan formula

tan (angle) = opposite/adjacent

tan (angle A) = BC/AC

tan (angle A) = 2.7/1.1

Angle A = tan inverse (2.7/1.1)

Angle A = 68°

Step 3: Find angle B

All 3 angles of a triangle are equal to 180°

Angle A + Angle B + Angle C = 180°

68 + B + 90 = 180°

Angle B = 22°

option a is the correct answer; ∠A = 68°, ∠B = 22°, AB = 2.9 cm

an isosceles triangle has angle measures of 55, 55, and 70. the side across the 70 degree angle is 10 inches long. how long are

Shtirlitz [24]

Answer:

The other sides of triangles are 8.72 in and 8.72 in

Step-by-step explanation:

In a triangle ABC. Please find the attachment for figure.

$\angle A=70^{\circ}$

$\angle B=\angle C=55^{\circ}$

Side BC=a = 10 in

Using sine law of trigonometry,

$\dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}$

Substitute the given value into formula.

$\dfrac{10}{\sin 70}=\dfrac{b}{\sin 55}=\dfrac{c}{\sin 55}$

$\dfrac{10}{\sin 70}=\dfrac{b}{\sin 55}$

Cross multiply and we get

$b=\sin 55\times \dfrac{10}{\sin 70}$

$b=8.72$ in

It is a isosceles triangle. Therefore, b=c=8.72 in

Hence, The other sides of triangles are 8.72 in and 8.72 in
