We know that
in the triangle ACB
∠ACB+90+34=180-----> ∠ACB=180-(90+34)----> ∠ACB=56°
∠ACD and ∠ACB-----> are supplementary angles
so
∠ACD+∠ACB=180-----> ∠ACD=180-56----> 124°------> x=124°
the answer Part 1) is x=124°
Part 2)
∠ACB+∠BCF+80=180-----> ∠BCF=180-(∠ACB+80)---> 180-(56+80)
∠BCF=180-136----> 44°-----> y=44°
the answer Part 2) is y=44°
Try to use long division! To calculate a fraction as a decimal, you can act like the slash is a division symbol.
So, to calculate 1/6 as a decimal, divide 1 by 6 on a sheet of paper (or a calculator) and you’ll find out what it is.
Answer:
The answer is 975
Step-by-step explanation:
Apply the sum rule: ∑an + bn = ∑an + ∑bn
First, fine the slope of the lines.
m=3-6/4-2
m=-3/2
To find the perpendicular slope of this, find the opposite reciprocal, or 2/3
Use formula y=mx+b to find the equation of this line.
3=(2/3)(4)+b
3=b+8/3
3-8/3=b+8/3-8/3
1/3=b
Now, plug in the values
y=2/3x+1/3, or B
Answer:
Subtract 63 from both sides
Step-by-step explanation:
we always have to try to clear the incognita that in this case is going to be h
First we
Subtract 63 from both sides
then
Divide by -7 on both sides
19 - 7h = 63
19 - 7h - 19 = 63 - 19
- 7h = 44
-7h/-7 = 44/-7
h = -44/7
