Answer: 3528.25
Step-by-step explanation:Make a sideview sketch
you should have 2 triangles, one right-angled containing the height and a scalene triangle with angles 24° , 153° (the supplement of 27°) and 3°
the side opposite the 3° angle is 1000
by let the side opposite the 24° be x, (also the hypotenuse of the right-angled triangle)
x/sin24 = 1000/sin3
x = 1000sin24/sin3
let the height of the mountain be h
sin 27 = h/x
h = x sin27 = (1000sin24/sin3)(sin27)
= 3528.25
Answer:
448
Step-by-step explanation:
Answer:
a = 127
Step-by-step explanation:
These angles are supplementary which means they add up to 180:
15 + a + 38 = 180
a + 53 = 180
a = 180 - 53
a = 127

Step-by-step explanation:
Answer:
her mother drives 142 miles more than her brother.
Step-by-step explanation:
227 + 337 = 564 miles in total driven
¼ of 564 miles = 136 miles (what her brother drives of the 564 miles)
564 - 136 = 428 left
her mother drives 428-150 miles from Wednesday = 278
278-136=142
