Answer:
Step-by-step explanation:
So we have the equation:
And we want to solve for R.
First, let's multiply both sides by J to remove the fraction on the right. So:
Simplify the right:
We can rewrite our equation as:
So, to isolate the R variable, divide both sides by I²t:
The right side cancels, so:
And we are done!
Answer:
see explanation
Step-by-step explanation:
Since the figures are similar then the ratios of corresponding sides are equal, that is
=
( cross- multiply )
9x = 72 ⇒ x = 8
Also
=
( cross- multiply )
6a = 45 ⇒ a = 7.5
And
=
( cross- multiply )
6b = 63 ⇒ b = 10.5
Corresponding angles in the 2 figures are congruent, thus
∠s = 83°
Each lower base angle is supplementary to the upper base angle on the same side, hence
∠r = 180° - 30° = 150°
