You need to know what type of triangle it is , all your triangles are right angles that means that they are 90° so you just need to subtract the number that its given from 90° ex
the first problem you just have to do this
21° - 90° = 79 °
so x = 79°

Answer:</h2>
<u>Given :</u> a = -10 and b = -4
<u>To prove :</u> a - b ≠ b - a
<u>Proof :</u> To put the values according to question,
- -10 - (-4) = -4 - (-10)
- -10 + 4 = -4 + 10
- -6 ≠ 6
Hence verified
Answer:Second Step
Step-by-step explanation:
On the right side in step two you added -3b-15b, and ended up with -12b. This is incorrect. -3b-15b is actually -18b
The answers are:
A) V-Shaped (because absolute value graphs are v-shaped)
C) Opens up (because the leading coefficient is positive)
F) Symmetric with respect to the y-axis (if you look at the graph y= |x|, you see that the y-axis cuts through the middle of the "v-shape", and that it is symmetric)
10 decreased by 5 equals 5
