Answer:
I/pr = t
Step-by-step explanation:
It's actually very simple:
~you have to make it into a distributive problem to get t from the other variables.
I= prt
I= t(pr)
Divide both sides by pr
I/pr= t(pr)/pr
I/pr = t
Yes the answer looks unfinished, but that is what literal equations look like in the end.
Make sure that I is capitalized or else you will get it wrong.
Answer:
(a) 4x=5(x-18)
(b) ∠A=∠B=360°
Step-by-step explanation:
Corresponding angles : when two lines are crossed by a transversal , the angle in matching corners are called corresponding angles.
Since the corresponding are congruent.
Therefore,
∠A=∠B
⇔4x=5(x-18)
⇔4x=5x-90
⇔4x-5x=-90
⇔-x=-90
⇔x=90
Therefore ∠A=∠B= 4×90°=360°
