Answer:

x = 70

Step-by-step explanation:

The chord- chord angle x is half the sum of the arcs intercepted by the angle and its vertical angle, then

x = $\frac{1}{2}$ (80 + 60) = 0.5 × 140 = 70

Solve each triangle for x.

Answer:

56 deg

Step-by-step explanation:

All internal angles of a triangle add up to 180 degrees

hence,

∠O + ∠R + ∠F = 180

x + (x+43) + (x-31) = 180

x + x+43 + x -31 = 180

3x+ 12 = 180

3x = 180 - 12 = 168

x = 168/3 = 56 deg

PLS help<br> solve for x: -6(2x-5) = 18

Mashutka [201]

Hey!

$-6(2x-5) = 18$

Switch it around and it becomes:

$2x - 5 = 18 \div -6$

First find 18 ÷ -6

$18 \div -6 = -3$

Positive ÷ negative OR negative ÷ positive is always negative.

That leaves you with:

$2x - 5 = -3$

Switch that around and it becomes:

$-3 + 5 = 2x$

Find -3 + 5

$-3 + 5 = 2$

That leaves you with:

$2 = 2x$

Divide both sides by 2 to leave <em>x</em> alone

$\frac{2}{2} = \frac{2x}{2}$

$\framebox{x = 1}$
