Answer: The measure of the first angle is 74.4 degrees.
Step-by-step explanation:
Let x be measure of the first angle and y be the measure of the second angle .
As per given , we have
Substitute the value of x from (2) in equation (1), we get
Put y= 15.6 in (2), we get
That means The measure of the first angle is 74.4 degrees.
Correct answer : The measure of the first angle is 74.4 degrees.
Answer:
y = & y= -
Step-by-step explanation:
The equation simplifies to 2.
How to solve-
PEMDAS shows that you will start off by multiplying. A negative times a positive equals a negative and a negative times a negative equals a positive.
-1 • 5= -5
and
-1 • -7 = 7
-5+7= 2
Answer:
9.76m²
Step-by-step explanation:
The area of the square is
where s=8m is the side length.
This means that:
The area of a circle is
From the diagram, the diameter is 8m.
This means that the radius is
The area of the circle then becomes,
The area of shaded region is area of square minus area of circle.
