Answer:

<1 = 55 degrees and <2 = 35 degrees

Step-by-step explanation:

Sum of complementary angles is 90.

<1 = 3x + 10

<2 = 4x - 25

3x + 10 + 4x - 25 = 90

7x - 15 = 90

7x = 105

x = 15

<1 = 3(15) + 10

<1 = 55

<2 = 4(15) - 25

<2 = 35

Help find the perimeter and area please

Answer:

P= 20.2 and A= 15.675

Step-by-step explanation:

The formula for the area of a triangle is 1/2 base*height. Therefore, the equation for the area of the triangle is 1/2*5.7*5.5. 1/2*5.7=2.85. 2.85*5.5=15.675(area). To find perimeter you're simply adding the numbers. When you add up the numbers of the triangle, you get 20.2.

Arturiano [62]

Cheeseburgers = 274
Hamburgers = 325

Divide 599 by 2 = 299.50 total burgers split in half
Divide 51 by 2= 25.50
Subtract 299.50- 25.50= 274cheeseburgers
Add 299.50+ 25.50= 325hamburgers

Answer:

(c).

Step-by-step explanation:

h(t) = - 16 t² + 80 t

Coordinates of the vertex are:

t = - $\frac{80}{2(-16)}$ = $\frac{5}{2}$ = 2.5 sec.
