Answer:
137°
Step-by-step explanation:
All angles in a triangle add up to 180° always.
Now imagine the two smaller shapes as a bigger triangle, CED. The measure of angle CED is 89°, and CDE is 48°. Do the math, and angle DCE is 43°.
But notice how the corresponding sides of the two smaller shapes are congruent. (CX=XE, and DY=YE) Meaning, the measure of angle C is equal to the measure of angle YXE.
We're almost there. CXY (what we're looking for) and YXE are supplementary angles, meaning the angle measures add up to 180. 180-43 = 137°.

this is your answer
You cant turn variables into numbers unless it tells you specifically what they equal. The answer to this is just 7h-70 because thats as far as you can simplify it.
Answer:

Step-by-step explanation:
Hello,
step 1 - we divide all terms by 2

step 2 - we complete the square
we can notice that

so

step 3 - we move the constant term to the right of the equation

step 4 - we take the square root on both sides of the equation

or

step 5 - we subtract 2 from both sides

or

so the solutions are 0.12 and -4.12
hope this helps
If you would like to solve the following system, you can calculate this using the following steps:
y = x - 20
y = 6 * x
_________
6 * x = x - 20
6 * x - x = -20
5 * x = -20 /5
x = -4
y = 6 * x = 6 * (-4) = -24
If you would like to solve the following system, you can calculate this using the following steps:
y = x + 20
y = 6 * x
_________
6 * x = x + 20
6 * x - x = 20
5 * x = 20 /5
x = 4
y = 6 * x = 6 * 4 = 24
