Step-by-step explanation:
Complementary angles together form a 90 degree angle. I don’t understand the question to well, but if two angles are next to each other and one of them is ten degrees, the other angle would be 80 is Together they form a right angle. Does my explain make sense? Sorry I hope this helps
Answer:
2W+2L=perimeter=74
Step-by-step explanation:
2W=74-2L
2(2W)+2(L/2)=76
substitute 74 - 2L for 2W in the last equation to solve for L. Put that value in the first equation to find W. Check by putting both values into the last equation.
Answer:
1. 10 degrees
2. x=35
3. x=20
Step-by-step explanation:
1. 90-80=10
a complementary angle is 90 degrees
2. 70/2=35
vertical angles are congruent
3. 90-30=60/3=20
it's a 90 degree angle
