Answer:
4a - 3b + 5 = 5
Step-by-step explanation:
Express the ratios in fractional form
=
( cross- multiply )
4a = 3b ( subtract 3b from both sides )
4a - 3b = 0
Then
4a - 3b + 5 = 0 + 5 = 5
Answer:
x° = 34°
Step-by-step explanation:
First, find the interior angle supplementary to the given exterior angle 124°.
I will label it y.
124° + y° = 180°
y° = 180° - 124°
y° = 56°
Next, solve for x° by equating the sum of the interior angles of the triangle to 180° and plugging in the y-value that we just solved for.
x° + y° + 90° = 180°
x° + y° = 90°
x° + 56° = 90°
x° = 90° - 56°
x° = 34°
