Answer:
m∠BAD = 144°
Step-by-step explanation:
Sum of interior angles of a quadrilateral = 360°
⇒ m∠A + m∠B + m∠C + m∠D = 360°
⇒ 4x + x + 2x + 3x = 360°
⇒ 10x = 360°
⇒ x = 36°
⇒ m∠BAD = 4x
⇒ m∠BAD = 4 × 36 = 144°
Answer:
m∠BAD = 144°
explanation:
a quadrilateral has total 360° interior angle.
<u>solve:</u>
↦ 4x + 3x + x + 2x = 360°
↦ 10x = 360°
↦ x = 360°/10
↦ x = 36°
<u>Find m∠BAD:</u>
↦ 4x
↦ 4(36)
↦ 144°

Answer:
x = 2 for a, c, and f
Step-by-step explanation:
a)
6(2x - 1) = 4 + 7x
12x - 6 = 4 + 7x
5x = 10
x = 2
b)
10 - 3x = -2(x + 4)
10 - 3x = -2x - 8
18 = x
c)
-3(7 - 2x) = -1 - 4x
-21 + 6x = -1 - 4x
10x = 20
x = 2
d)
7x + 12 = 2(4x - 5)
7x + 12 = 8x - 10
22 = x
e)
-5(x + 1) = -4 - 7x
-5x - 5 = -4 - 7x
2x = 1
x = 1/2
f)
8x + 11 = 9(5 - x)
8x + 11 = 45 - 9x
17x = 45 - 11
17x = 34
x = 2
The angles that are congruent are b. 60 and 60
