Answer:

21°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

subtract the sum of the 2 given angles from 180 for the other angle

other angle = 180° - (90 + 69)° = 180° - 159° = 21°

If r/s = 22 and the value of r is 242, what is the value of s

jekas [21]

Answer:

s = 11

Step-by-step explanation:

Given

$\frac{r}{s}$ = 22 ← substitute r = 242

$\frac{242}{s}$ = 22 ( multiply both sides by s )

242 = 22s ( divide both sides by 22 )

11 = s

Can somebody help me on these two

Zarrin [17]

to find the slope for the first one, use the formula $\frac{y2-y1}{x2-x1}$

(It's the slope formula)

so... $3=y2, 3=y1, 2=x2, 10=x1$

then plug in... $\frac{3-3}{2-10} =\frac{0}{-8} = 0$

this line has a slope of 0

As for the miles problem, to find mph, the miles have to be at 1.

so... $4x=242\\x=60.5$

therefore, he drove 60.5 mph
