Solve tor r.<br> *a(5 – x) = bz - 8

Mars2501 [29]

Answer:

See explanation

Step-by-step explanation:

Assuming the given equation is

$a(5 - r) = bz - 8$

To solve for r, we first divide both sides by a.

$5 - r = \frac{ bz - 8}{a}$

We now subtract 5 from both sides:

$- r = \frac{ bz - 8}{a} - 5$

We now divide through by - 1 to get:

$r = 5 - \frac{ bz - 8}{a}$

$r = \frac{5a - bz + 8}{a} \: \: where \: a \ne0$

sergeinik [125]

Answer:

Step-by-step explanation:

When two angles add up to 90, they are complementary angles

∠a + ∠b = 90

59 + ∠b = 90

∠b = 90 - 59

∠b = 31°
