Answer:
m∠XBC = 135
Step-by-step explanation:
What is the measure of ∠XBC?
m∠XBC = m∠BAC + m∠BCA
3p – 6 = p + 4 + 84
3p – 6 = p + 88
2p – 6 = 88
2p = 94
From the simplified expression, we need to find the value of p first
From the last line we can see that;
2p =94
Divide both sides by 2:
2p/2 =94/2
p = 47
From the expression, m∠XBC =3p-6
m∠XBC = 3(47)-6
m∠XBC = 141 -6
m∠XBC = 135
Hence the measure of m∠XBC is 135
Answer:
1. (B) 73
2. r = 15
Step-by-step explanation:
1. The sum of angles in a triangle is 180°.
62° +45° +k° = 180
k = 180 -107
k = 73
__
2. The sum of exterior angles of any polygon is 360°.
4r° +7r° +5r° +8r° = 360°
24r = 360 . . . . . . . . . . . . . collect terms, divide by °
r = 360/24 . . . . . divide by 24
r = 15
