The sum of the measures of ∠QRT and ∠TRS is 180∘. What is the measure of ∠TRS If ∠TRS = ∠QRT?

Bad White [126]

Let the angles be x

∠QRT = x
∠TRS = x

We are taking both angles as x because they are equal!

$\mathcal{∠QRT + ∠TRS = 180 \degree}$

$\tt \: x + x = 180 \degree$

$\tt \: 2x = 180 \degree$

$\tt \: x = 90 \degree$

➪ Thus, The measure of both angles is 90°...~

X/a+x/b=1 make x the subject of the formular

monitta

Answer:

x = $\frac{ab}{b+a}$

Step-by-step explanation:

Given

$\frac{x}{a}$ + $\frac{x}{b}$ = 1

Multiply through by ab to clear the fractions

bx + ax = ab ← factor out x from each term on the left side

x(b + a) = ab ← divide both sides by (b + a)

x = $\frac{ab}{b+a}$
