Step-by-step explanation:
Answer:
50 degrees
Step-by-step explanation:
The total sum of angles in a triangle is 180, thus the value of ∠ACB will be obtained as follows:
Given that the triangle is a right triangle, the sum of angles will be:
(4x)°+(7x-20)°+90=180
simplifying and solving for x we get:
4x+7x-20+90=180
11x=180+20-90
11x=110
dividing both sides by 11 we get:
(11x)/11=110/11
this gives us
x=10°
Thus substituting the value of x in:
∠ACB=(7x-20)°
=(7*10-20)
=70-20
=50°
Answer: 50°

Step-by-step explanation:
you have to subtract the little number from the big number
Answer:
0.14875
Step-by-step explanation:
First you would need to convert 7/8 into a decimal by dividing 7 by 8.
7 divide by 8 is 0.875
Then add 14 and 0.875 which is 14.875%
Now you need to convert 14.875 into a decimal by moving the decimal two spaces to the left.
So 14 7/8% converted to a decimal is 0.14875
a.
Solution Given:
Slope of the line passing through the point is
m=
<u>slope=-2</u>
b.
Solution given:
equation is
2x-5y=-10
2x+10=5y
y=2x/5 +10/5
y=2/5 x +3
comparing above equation with y=mx+c
we get
m=2/5
<u>slope=2/5</u>
c.
Slope of the line passing through the point is
m=
-4=
-4=10/-x
doing criss cross multiplication
-4*-x=10
4x=10
x=10/4
x=5/2
<u>slope=5/2</u>
d.
we have
equation of line passing through the one point is
y-5=-7(x-(-1))
y=-7(x+1)+5
y=-7x-7+5
<u>y=-7x-2 is a required equation:</u>
