Answer:
4900
Step-by-step explanation:
70^2 means 70*70
70*70=4900
Supplementary angles are 180 in total, so to find the answer you do 180-10, which equals 170. The answer is 170
Hello.
We are solving -9.4 > 1.7x + 4.2.
First we need to swap sides:

Now we need to subtract 4.2 from both sides.
1.7x + 4.2 = -9.4
-4.2 . -4.2
Now let's combine -4.2 + 4.2 which is 0.
We get 1.7x < -9.4 - 4.2
Now let's divide both sides by 1.7
1.7x | -13.6
1.7 1.7
x < -13.6
1.7
So we just divided to get x < -8.
Answer:
CED=126
Step-by-step explanation:
The total of all 3 angles should be 180
so:
180-38-16 (ABC is equal to ECD)
180-38-16=126
126=CED
Answer:
x=5, y=(5)/2
Step-by-step explanation:
Using the 30-60-90 triangle rule, we know that the sides follow 1-(/2)-2. The ratio between the side and the rule is 5/2, meaning that we know that y=(5)/2 and x=5.
