Answer:
Perimeter is 38.8 units and approximately 39 units
Step-by-step explanation:
Trust me :)
We solve the equation: a = 50 + ( 90 - a );
Then, a = 140 - a;
2a = 140;
a = 140/2;
a = 70 (it is the measure of one angle);
90 - 70 = 20 (it is the measure of another angle);
Answer:
(C) m∠A′B′C′ = m∠ABC
Step-by-step explanation:
Regardless of what translation or transformation you do to this shape, the angles will always stay the same.
Once again if the numbers after x are supposed to be exponents(the raising power) then the answer will be -5
