Answer:

The correct answer is m∠2 = 120°

Step-by-step explanation:

There is a triangle rule that states the outer angle of an angle in a triangle is equal to the sum of the remaining two angles in that triangle, which means that m∠2 = 52° + 68° = 120°. This can be proven correct because the sum of two of the angles in the triangle is 120°, which means the final angle is 60°. Since m∠2 is the outer angle of 60°, that means it will be 180° - 60° or 120°.

Zinaida [17]

Answer:

Principal = $500

Interest = $37.50

Rate = 0.025 = 2.5%

Time = 3 years

Step-by-step explanation:

The formula for simple interest is I = PRT ÷ 100

Casandra's equation = I= 500(0.025)(3)=$37.50

Principal = $500

Interest = $37.50

Rate = 0.025 = 2.5%

Time = 3 years

Solve the following formula for t. F=J+Jrt

kherson [118]

First, we separate all instances of t by subtracting J from both sides:

F = J + Jrt
F - J = Jrt

Then, we separate the t by dividing both sides by Jr:

$\frac{f - j}{jr} = t$
Therefore, t is equal to (F - J) ÷ Jr

Temka [501]

Answer:

Population is 34000 students

Sample is 770 students

Step-by-step explanation:

Population :In statistics, a population is the entire pool from which a statistical sample is drawn.

Sample: A sample refers to a set of observations drawn from a population.

We are given that 34,000 students attended the university.

Out of which a random sample of 370 male students and 400 female students was selected

So, Total students selected = 370+400=770

So, Population is 34000 students

Sample is 770 students

So, Option C is true.

The height of a triangle is 4 feet more than 3 times the base. If the area is 112 ft find the base and height of the triangle

Finger [1]

Answer:

$base = 8 ft\\height =28 ft\\$

Step-by-step explanation:

let base be x ft. then the height is 3x+4

$Area=\frac{1}{2} \times x \times (3x+4)=112\\3x^{2} +4x=224\\3x^{2} +4x-224=0\\x=8, x=-9.33 (no sol. as length can not be negative)\\ x=8\\base = 8 ft\\height =3(8)+4=28 ft\\$
