Answer:

21°, 84°, 75° are the angles

Step-by-step explanation:

Total angle in a triangle is 180.

x + 4x + (5x - 30) = 180

10x - 30 = 180

10x = 210

x = 21°

Angles are:

A: 21°

B: 4(21) = 84°

C: 5(21) - 30 = 75°

Find the perimeter of the parallelogram *<br> 10 inches<br> 5 inches<br> 8 inches

Paladinen [302]

Step-by-step explanation:

We know that in a parallelogram

Opposite sides are of equal length

<h3>The sides are,</h3>

$\\ \:\:\:\:\sf {:}\dashrightarrow 5in,10in,10in,5in$

$\boxed{\sf Perimeter=Sum\:of\:all\:sides}$

$\\ \:\:\:\:\sf {:}\dashrightarrow Perimeter_{(Parallelogram)}=5+5+10+10$

$\\ \:\:\:\:\sf {:}\dashrightarrow Perimeter_{(Parallelogram)}=10+20$

$\\ \:\:\:\:\sf {:}\dashrightarrow {\underline{\boxed{\bf Perimeter_{(Parallelogram)}=30inches}}}$

circle F is intersected by line HI and IJ and the measurement of angle HIJ is 101 degrees. what is the measurement of arc HJ

Colt1911 [192]

To solve this problem, you need to use the Exterior Angle (Out) equation which for this problem would be $\frac{281-x}{2}=101$ . After correctly solving the problem with this equation, you will figure out that the answer is 79.

mHJ= 79°

Hope this helped :)
