Answer:60°
Step-by-step explanation: First, think about the rule of the degrees for all triangles. Angles must equal 180°.
Second, because all angles must equal 180°, see that the triangle given has equal sides (assuming this, because no other measurements are given).
Equilateral triangles have equal angles, meaning 60° for each angle.
Answer:
a = 4
Step-by-step explanation:
8 = 5a > - 12
8 + 12 = 5a > - 12 + 12
20 = 5a
20 ÷ 5 = 5a ÷ 5
a = 4
Check:
8 = 5(4) < 12
8 = 20 < 12
It is correct.
Answer:
<em>h = 6.2</em>
Step-by-step explanation:
You need to find h.
The dashed triangle is a right triangle. 8 is the hypotenuse. h is a leg. The other leg is the half of the side of the base, 5.







So multiply 128 by 15 to get 1920 and then move the decimal over two places to get 19.20 and then subtract that $19.20 from $128 to get $108.8
