HELP!

emmasim [6.3K]

A) Divide the total height by the average height:

26.4 / 1.2 = 22 total boys.

B) Divide total feet by total time:

440 feet / 20 seconds = 22 feet per second.\

Because the submarine is diving the rate would become negative 22 feet per second.

The measure of Angle d is 150°. What is the value of Measure of angle b + measure of angle c + measure of angle e?

horrorfan [7]

Answer:

$\angle b + \angle c + \angle e = 120^\circ$

Step-by-step explanation:

Given

$\angle d = 150$

See attachment for illustration

Required

Find $\angle b + \angle c + \angle e =$

The sum $of\ angles\ at$ a point is $360^\circ$

So:

$\angle a + \angle b + \angle c + \angle d + \angle e = 360^\circ$

Angle a is at right angled.

So:

$90 + \angle b + \angle c + 150 + \angle e = 360^\circ$

Collect like terms

$\angle b + \angle c + \angle e = 360^\circ -150^\circ - 90^\circ$

$\angle b + \angle c + \angle e = 120^\circ$
