Answer:

45 degree , bc the ends are all 90 degree so divide 90 by two since the line crosses right in between

Answer:

45°

That looks like an Isosceles triangle so two sides are equal

The angle near O would be 90° cause that looks like an right angle

180-90=90

To find each angle divide by 2

90÷2=45

Area of the rectangle

$= l \times b$

$= 8 \times 6$

$= 48 {in}^{2}$

Area of the semicircles

$= 2 \times ( \frac{1}{2} \pi {r}^{2} )$

$= \pi {r}^{2}$

$= \pi {3}^{2}$

$= 9\pi$

$= 9 \times 3.14$

$= 28.26 {in}^{2}$

Area of the figure

$= 48 + 28.26$

$= 76.26 {in}^{2}$

= 76.3in²

Jerry can eat 24 hot dogs in 6 minutes. They want to know how many minutes (m) it would take them to eat 35 hot dogs if they can

scZoUnD [109]

Answer: 8 minutes and 45 seconds or 8.75 minutes

Step-by-step explanation:

Find hot dogs per minute

24/6=4 hot dogs per minute

35/4=8.75

So jerry needs 8 minutes and

60x0.75= 45 seconds

Find the value of x in the given statement. The diagram is not to scale.

Evgen [1.6K]

Step One
Find RST
The two base angles are given as equal and one of the is 28. So is the other one.
SRT = 28
STR = 28
All triangles have interior angles that add up to 180 degrees.

RST + SRT + STR = 180
28 + 28 + RST = 180
56 + RST = 180 Subtract 56 from both sides.
RST = 180 - 56
RST = 124

Step two
Find the exterior angle
The exterior angle = Sum of the two remote interior angles (RST + SRT)
The exterior angle = 28 + 124
The exterior angle = 152

Step Three
Find the value of x
2*x = 152 Divide by 2
x = 152 / 2
x = 76

There is a quicker way of finding the exterior angle. I didn't see it until I had written step two.
The exterior angle + STR = 180 degrees. They are supplementary.
The exterior angle + 28 = 180
The exterior angle = 180 - 28
The exterior angle = 152
