Answer:
c. 80
Step-by-step explanation:
cos x = sin(x-70)
cos x = cos [90-(x-70)]
cos x = cos (90-x +70)
cos x = cos 160 -x
x= 160-x
2x = 160
x =80
Answer:
DIVIDING 9 AND 5 = 23.8
9/5 FRACTION = 0.04
Step-by-step explanation:
If 9/5 means 9 divided by 5
FLIP THE EQUATION
9/5C + 32 = 75
9/5C + 32 - 32 = 75 -32
9/5C = 43
9/5 = 1.8
1.8C = 43
1.8C/1.8 = 4
If 9/5 means 9/5ths fraction
FLIP THE EQUATION
9/5C + 32 = 75
9/5C + 32 - 32 = 75 -32
9/5C = 43
9/5C / 9/5 = 43 / 9/5
C = 0.04
Hope this helps i thought 9/5 was 9 divide by 5. If it was 9/5 as a fraction i also made that equation too.
Answer:
y=2x-2
Step-by-step explanation:
y=mx+b is point slope form.
let m= the slope
b=y intercept
the y intercept is -2
y=mx-2
then after finding the slope (2) put that in
y=2x-2
We know that
in a right triangle
Applying the Pythagoras Theorem
c²=a²+b²
in this problem
c=√87 yd
a=√23 yd
b=?
so
b²=c²-a²-----> b²=(√87)²-(√23)²----> b²=87-23----> b²=64----> b=8 yd
the answer is
8 yd
Answer:
y = (1/5)x - 8
Step-by-step explanation:
It's slope-intercept form y=mx+b and we just substitute m=1/5, b= -8.
