Can someone please help me with this (thank you)
pickupchik [31]

Answer:

D. ( 3.6 , 2.2)

Step-by-step explanation:

Given

x + y = 5.8....equation 1

y = 2x - 5 ......equation 2

Putting equation 2 in equation 1

x + 2x - 5 = 5.8

3x = 5.8 + 5

3x = 10.8

Therefore x = 3.6

Now

y = 2 * 3.6 - 5

= 7.2 - 5

= 2.2

Hope it will help you.

Just do 3x+5+2x=90 And solve for x.

So, 5x+5=90
5x=85
x=85/5 = 17

now you know the value of x, so you can calculate the angles.

Btw the total angle of a triangle is 180, and since this is a right angle triangle, you know that the two angles added together needs to equal 90.
