What is the measure of 21? 100° 90° 80° 85° 95%​
Scorpion4ik [409]

Answer:

A quadrilateral's interior angles have a sum of 360°.

Given that we have 85°, 100°, and 90°(the right angle), and an unknown angle.

We can add these angles plus the unknown angle to equal a total of 360°.

85 + 100 + 90 + x(our unknown missing angle) = 360

simplify

275 + x = 360

Isolate x by subtract 275 from both sides;

-275       -275

x = 85, ∠1 = 85°

We can also double check:-

85 + 100 + 90 + <u>85</u> = 360

360 = 360 which is correct.

Find the solution of this system of equations. <br> -2x-6y=-16<br> 4x-6y=-58
Yanka [14]
-(-2x-6y=-16)

2x+6y=16
4x-6y=-58

Y's cancel out, then add the rest

6x=-42

divide both sides by six

x=-7

plug x into any previous equation

2(-7)+6y=16

-14+6y=16

6y=30

y=5
