Answer:

∠ A'OB' = 79°

Step-by-step explanation:

∠ AOC = ∠ C'OA' = 35° ( vertical angles )

BOB' is a straight angle , thus

∠ COB' = 180° - (79 + 35)° = 180° - 114° = 66°

C'OC is a straight angle, thus

∠ A'OB' = 180° - (66 + 35)° = 180° - 101° = 79°

Solve for b, then solve for each angle in the triangle

lesya692 [45]

We know that the sum of the interior angles of a triangle equals 180, then,in this case we have the following equation:

$b+2b+(b+16)=180$

then, solving for b, we get:

$\begin{gathered} b+2b+(b+16)=180 \\ \Rightarrow4b+16=180 \\ \Rightarrow4b=180-16=164 \\ \Rightarrow b=\frac{164}{4}=41 \\ b=41 \end{gathered}$

now that we have that b = 41, we can find the measure of each angle:

$\begin{gathered} b=41 \\ 2b=2(41)=82 \\ b+16=41+16=57 \end{gathered}$

‼️‼️any help I would appreciate

Hey there!

In an isosceles triangle the 2 base angles are congruent, therefore angle B would measure 50 degrees just like the measure of angle A.
