A)
Because the sum of angles in a triangle must equal 180° we can say:
62+α+90=180
α+152=180
α=28°
b)
Since all sides have equal length, all angles must have equal measure. (This is an equilateral triangle). And again, because the sum of the angle must be 180° we can say:
b+b+b=180
3b=180
b=60°
Answer:
We would need pictures of the figures first :(
Answer:
false
Step-by-step explanation:
consider y = 3
its 6 for one and 3 for the other
((b1+b2)÷2)(h)=A
so I think the answer is 3 1/16 or 3.0625
Answer:
Ok im, not 100% sure but the answer is for 1-10, 2-20, 3-40, 4-40
