Complentary angles add to 90 degrees
a and b are complentary
a+b=90
a=7x+4
b=4x+9
so
7x+4+4x+9=90
combine like terms
11x+13=90
minus 13 both sides
11x=77
divide both sides by 11
x=7
m a =7x+4=7(7)+4=49+4=53
m b=4x+9=4(7)+9=28+9=37
angle a measures 53 degrees
angle b measures 37 degrees
Answer:
Step-by-step explanation:
Part A
Part B
- 5.50x = 62.50 - 35
- 5.50x = 27.50
- x = 27.50/5.50
- x = 5
Answer:
y= x + 4 is the answer
Step-by-step explanation:
y-int= 4
slope = 1
So it the first choice
Answer part A:
-6°F
Answer part B:
-7,5°F
Step-by-step explanation:
- A: 7-13= -6
- B: 11-5= 6 ==> 6*(-1,25)= - 7,5
I believe the answer would be 2xyz9x2yz18x2 - 6y4x3 + 5ab - 4. the x canceled itself out.
