What is the area of this polygon? Please explain!

Mathematics

to find the area, it helps to know all the lengths.

The vertical (V) piece near the 9 equals 2 and the horizontal (H) piece equals 6.

(to find the V piece, I did 10-8; for the H piece I did 15-9)

Next you have to find the area. I find its easiest to split them up into more shapes so I had a big rectangle and the little square piece at the bottom.

The measurements to multiply for the rectangle are 15*8= 120

the measurements for the little square are 9*2=18

Then you add the two numbers together 120+18=138.

The area is 138m

Angle A and angle B are complementary angles. If m∡a = 4x and m∡b = 3x +13, what is the measure of the smaller angle?
bagirrra123 [75]

Answer:

Step-by-step explanation:

Complementary angles mean two two angles sum with equal 90 degrees. Therefore you would need to create an equation to solve for the value of x.

4x+3x+13=90

-13 -13

7x=77

/7 /7

X=11

Now plug in the value of x.

A=4(11) B=3(11)+13

A=44. B=33+13

B=46

Angle a is the smaller angle and measures at 44°

21. Angela until the same restaurant four times. Each time she ordered a salad and left at $ 5 tip. She spent a total of $ 54. W
Natalka [10]

So if Angela entered the same restaurant 4 times, we have 4 "instances" of her entering the restaurant.

Each instance, she ordered a salad. The price of this salad is unknown, so we'll say the price is "S".

Each instance, she payed a $5 tip.

So we have 4 instances of spending S, and 4 instances of spending 5.

We know this totals 54.

Knowing all of this information, we can write our equation like this:

4(S + 5) = 54

Divide

S + 5 = 13.50

Subtract

S = 8.50

The cost of salad is $8.50
