Answer:
p : q : r = 10 : 4 : 3
Step-by-step explanation:
Expressing the ratio in fractional form
= ( cross- multiply )
4r = 3q ( divide both sides by 4 )
r = q = × 2 =
Then
p : q : r
= 5 : 2 : ( multiply all parts by 2 )
= 10 : 4 : 3
10=-3k+8k
10=5k
10/5=5/5k
2=k
Answer:
∠x = 72°
Step-by-step explanation:
since two sides are equal, their opposite angles are equal.
Then the upper angle is also equal to 54°.
All triangle angles add up to 180°.
∠x = 180 - 54 - 54 = 72°
