I NEED HELP ASAP PLS

Step-by-step explanation:

The sum of the measures of the angles in a triangle is 180°. The equation relating angles 1, 2, 3 will reflect this fact.

  m∠1 +m∠2 +m∠3 = 180°

__

Of course, angle 3 is supplementary to angle 4, so we have ...

  m∠3 +m∠4 = 180°

Substituting this expression for 180° in the first equation, we have ...

  m∠1 +m∠2 +m∠3 = m∠3 +m∠4

Subtracting ∠3 from both sides, we are left with an equation relating angles 1, 2 and 4.

  m∠1 +m∠2 = m∠4

__

The "rule" expressing this last relationship is, "an exterior angle is equal to the sum of the remote interior angles." Knowing this relation can make a number of problems easier to solve.

the correct answer is semicircle

step-by-step explanation:

the answer is semicircle because the shorter arc joining two points on the circumference of a circle is known as the minor arc, the larger arc is called the major arc, and a semicircle is a half circle, formed by cutting a whole circle along a diameter line.

hope i .

answer: the answer is 30 miles per hour.

ft/s -> mphmph = ft/s 1.466667mph = 44 divided by 1.466667mph = 30.00000
