For any triangle, the 2 shortest sides added together have to be longer than the longest sides.
short side (10) + short side (5) needs to be greater than (>) longest side (20)
10 + 5 > 20
15 > 20
This inequality is incorrect, so the lengths cannot make a triangle.
Hope this helps :)
Answer:
m∠8 = 123°
Step-by-step explanation:
<em>∠1 and ∠8 are alternate exterior angles</em>, and since lines A and B are parallel, then <em>they must be congruent</em>.
So, m∠1 = m∠8
Substitute: 123 = m∠8

Answer:
21sq
Step-by-step explanation:
multiply the l times the w which would be 3x7 and get 21.
Bh + hr = 25
you can factor out an h from the left side of your equation:
h(b + r) = 25 ... divide both sides by h
b + r = (25/h) ... subtract r
b = (25/h) - r
