Answer:
∠A = ∠B = 80°
Step-by-step explanation:
The angles are corresponding angles where a transversal crosses parallel lines, so are congruent. That means ...
∠A = ∠B
8x -8° = 5x +25° . . . . . substitute the given expressions
3x = 33° . . . . . . . . . . . . add 8°-5x
x = 11° . . . . . . . . . . . . . . divide by 3
Then the angles are ...
8·11° -8° = 80°
You can fit 15 2cm in a 600mm by 500mm.

Answer:
<h2>
a = 51.4</h2><h3>
</h3>
Step-by-step explanation:
<u>sinA</u> = <u>sinB</u>
a b
<u>sin(117)</u> = <u>sin(12)</u>
a 12
a * sin(12) = 12 * sin(117)
a = <u>12 * sin(117)</u>
sin(12)
a = 51.4
Answer:
ΔABC ≅ ΔEDF by SSS
Step-by-step explanation:
Its not a right triangle so it cant be the 2nd or last one.
ABC is equal to EDF, if you trace where the lines go
it is not equal to fde
