Step-by-step explanation:
Answer:
t = 0.53 hr
Step-by-step explanation:
We write expressions for the distances walked by these two people, sum them up and set the sum equal to 4 miles:
(3.5 mph)(t) + (4mph)(t) = 4 mi
Combining these terms:
(7.5 mph)(t) = 4 mi
4 mi
Solving for t: t = ---------------- = 0.53 hr
7.5 mph
Answer:
x = 12.17
Step-by-step explanation:
we use the tan function
Answer:
m∠4=160°
m∠6=20°
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
m∠6+m∠4=180° ----> equation A (by consecutive interior angles)
m∠6=(1/8)m∠4 ---> equation B
substitute equation B in equation A
(1/8)m∠4+m∠4=180°
Solve for m∠4
(9/8)m∠4=180°
m∠4=180°(8)/9
m∠4=160°
<em>Find the measure of m∠6</em>
m∠6=(1/8)m∠4
m∠6=(1/8)(160°)=20°
