Answer:
51°
Step-by-step explanation:
Given
<QPR = 39°
<PQR = 90° ( inscribed angle in semi circle)
Now
<QPR + <PQR + <PRQ = 180° { being sum of angles of triangle)
39° + 90° + <PRQ = 180°
<PRQ = 180° - 39° - 90°
<PRQ = 51°
Hope it will help :)
The slope of the given line = 1 so the slope of the line perpendicular to it will be -(1/1) = -1.
It also passes through point (1, -1) so we use the point slope equation
y - y1 = m(x - x1)
y - -1) = -1(x - 1)
y + 1 = -x + 1
y = - x <--------- that's the answer
Answer:
9 miles
Step-by-step explanation:
234-72= 18m
234- 72= 162
162/18= 9 miles
Y=X/5
Step-by-step explanation:
Step 1:
Let X be the input and Y be the output variable
Given: the output is one-fifth of the input
Step 2:
Y=X/5 be the require function
Eq:
for X=1, Y = 1/5
X=2, Y=2/5, etc
The missing factor is 20. 10 x 20 = 200
