Answer:
C.
Step-by-step explanation:
Integers are rational numbers.
A + B = m/q + n/p = (mp + nq)/pq
To solve hg = 45g
Apply Multiplication Property of Equality which is to multiply both sides of the equation with 1/g.
hg (1/g) = 45g (1/g)
h = 45
Or you can divide both sides with the equation with g.
hg / g = 45g / g
You can cancel g to both sides.
Then,
h = 45
Answer:
a = 84°
Step-by-step explanation:
∠ QPR and ∠ TPR are adjacent and supplementary, thus
∠TPR = 180° - 123° = 57°
Given there are parallel lines , then
∠ PTR = 27° ( alternate angle )
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ TRS is an external angle , thus
∠ TRS = a = 57° + 27° = 84°
