Answer:
x=40° and y=50°
Step-by-step explanation:
45°+50°+2x+5=180°
100°+2x=180<-- subtract 100 to get x on one side
2x=80
x=40. Thus 2(40)+5 = 85.
85°+55°+x°=180
140°+x=180
x=40°
40°+90°(right angle)=130°, so 180 -130 would equal 50.
y=50°
Answer:
Coefficient
Step-by-step explanation:
If it is 10a^3 (10 times the variable "a" cubed), then 10 is the coefficient.
A+b+c=-44.84
a=26.6
b=c
26.6+b+b=-44.84
2b=-44.84-26.6
b=-35.72
So, a=26.6, b=-35.72, c=-35.72
You can do this with foil
F(which is the first term of both factors): 4*sqrt(7)
O(outside terms of both factors first and last) 4*sqrt(2)
I (Inside terms 2nd and 3rd) = - sqrt(3) sqrt(7) = - sqrt(21)
L (Last term in each of the factors) - sqrt(3)*sqrt(2) = - sqrt(6)
Combine terms: 4*sqrt(7) + 4*sqrt(2) - sqrt(21) - sqrt(6) <<<< answer.
Step-by-step explanation:
x+ 2(7-x) = 11
x+14-2x = 11
-x = -3
x = 3
3+ y = 7
y = 4
x + 2(22-x) = 48
x + 44 -2x = 48
-x = 4
x = -4
-4 + y = 22
y = 26
y = 45-x
x + 2(45-x) = 36
x + 90 -2x = 36
-x = 54
x = -54
-54 + y = 45
y = 99
