Answer:
C. 60 degrees, 60 degrees, 60 degrees
Step-by-step explanation:
The measures of interior angles of a triangle sum to 180°.
Answer:
The domain is all real numbers
Step-by-step explanation:
In any infinite quadratic equation, the domain is all real numbers.
Find the area of each shape and add.Let's start with the first semi-circle(half-circle)
If the area of a circle is πr² , then the area of a semi-circle is 1/2πr² where is 22/7 or 3.14, and r is the radius which is 1.8 meters
A=1/2πr²
A=1/2*22/7*1.8*1.8
A=5.09 m²(rounded to nearest hundredth)
Since the semi-circles are two and have the same radius, multiply the area of the first one by two or go through the same process again.
So 5.09 *2=10.18meters square is the area of the two semi-circles
Now, let's find the area of a rectangle which is length times width, where length is 6 meters and width is (1.8+1.8, because 1.8 is half the width)=3.6 meters
A=l*w
A=6*3.6
A=21.6meters square
Therefore the area of the shape is 10.18m²+21.6m²=219.888m²
Answer:
<u>93°</u>
Step-by-step explanation:
According to angle sum property, all the internal angles of a triangle add up to 180 degrees.
=> 37 + 50 + ? = 180
=> ? = 180 - 87
=> ? = <u>93°</u>
