If we know that line 
is equal to line 
, then this means that ∠
has to be equal to ∠
in order to form a closed triangle. All angle measures of a triangle add up to 
°, so use the equation: 
.
70 + x = 180
Subtract 70 from both sides to isolate x:
180 - 70 = 110
110 = x
Hope this helped.

Answer:
10
Step-by-step explanation:
1. The area of triangle is = (A*h)/2, where h is the height grounded on side A.
2. Given the height 5 and the side 4 we get S(area)=(5*4)/2=10.
