Answer:

1. measure of angle E is 90 degrees

2. Measure of angle F + measure of angle G is 90 degrees

Step-by-step explanation:

Angle E is 90 degrees because it is marked as a right angle (the square)

A triangle has 180 degrees so if E is 90 degrees then the other 2 also have to equal 90 degrees

Uhh help lol<br> 5.3x + y = 28.5 <br> 4.2x + 3.1y = 27.2<br> find x and y

navik [9.2K]

Answer:

x = 5, y = 2

Step-by-step explanation:

First, isolate y in the top equation.

$y = -5.3x+28.5$

Next, substitute y in the bottom equation.

$4.2x + 3.1(-5.3x + 28.5) = 27.2$

$5.3x + y = 28.5$

Simplify.

$4.2x + -16.43x + 88.35 = 27.2$

Combine like terms.

$-12.23x + 88.35 = 27.2$

Isolate x on one side.

$-12.23x = -61.15$

Isolate x.

$x = 5$

Substitute x into $5.3x + y = 28.5$

$5.3(5) + y = 28.5$

Simplify.

$26.5 + y = 28.5$

Isolate y.

$y = 2$

$x = 5 \\y = 2$
