The bottom line is a straight line that is equal to 180 degrees.
The three angles above it all need to add together to equal 180.
One angle is given as 20, so the other two need to add together to equal 160 ( 180-20 = 160)
Those two angles form the angle ACE so the answer would be 160 degrees,
Answer 160 degrees.
Answer:X=11/10
Step-by-step explanation:
2x2-10x+7=0
<u><em>4</em></u>-10x+<u><em>7</em></u>=0
11-10x=0
-10x= -11
Divide both side by -10
-10x/-10. -11/-10
Answer= 11/10

Answer:
x=28
Step-by-step explanation:
The interior angles of a triangle must add to 180 degrees
Therefore,
79+73+x=180
Combine like terms by adding 79 and 73
152+x=180
To solve for x, get x by itself. Since 152 is being added to x, subtract 152 from both sides. This will cancel the 152, and leave x by itself.
152-152+x=180-152
x=28
So, x is equal to 28 degrees
