Answer:
Step-by-step explanation:
<u>Question 1</u>
Two isosceles triangles with repeat 72°.
- x = 180° - 2*72°
- x = 180° - 144°
- x = 36°
<u>Question 2</u>
Isosceles triangle with repeat x/2 angle and a x angle.
- 2(x/2) + x = 180°
- 2x = 180°
- x = 90°
78+82+s/3
=160+s/3

6 lb = 96 oz
2 lb = 32 oz
96 + 4 = 100
32 + 10 = 42
100 - 42 = 58
58 oz
58 / 16 = 3 10/16
3 lb 10 oz
Answer: 3 lb 10 oz
Answer:
Option C. 
Step-by-step explanation:
we have
Solve for x
That means ---> isolate the variable x
Multiply by 8 both sides to remove the fractions
Multiply by -1 both sides
Remember that
When you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol
Divide by 5 both sides
Answer:
80 degrees
Step-by-step explanation:
Sum of the interior angles of a triangle = 180
a + 50 + 50 = 180
a = 80
