Answer: The measure of angle S is 62 degrees.
There are 2 ways to find the answer.
First, the triangles are similar. That means that all the angles will be the same. Since, angle S is corresponding to angle B, it will have the same measure.
Second, there are always 180 degrees in a triangle. Therefore, we can write and solve the following equation about the angles in triangle SQR.
x + 41 + 77 = 180
x + 118 = 180
x = 62
1.5
negative times a negative is a positive
4x3/8=1.5
Answer:
x = 120
Step-by-step explanation:
First you want to get the equation into the form cosx = a
2 cos
=1
Divide both sides by two to get it into the form.
cos= 
Now, on your calculator, use the inverse of cos, to solve for .
= 
( )
= 60
Now you want to find x, so multiply both sides by 2.
x = 60 * 2 = 120
x can have many solutions; however, I have only given you one.
7. To find the area of a triangle you use base x height /2. so the base is 10 and the height is 25 so you do 10 x 25 first which is 250 then divide by 2 which gives you 125 so the area of each pennant is 125 cm^2 ( the ^2 means squared)
8. To find the area of a square you do length x Width. Since for a square all sides are the same the length AND the width are both 450cm. Now you just do 450 x 450 which gives you 202,500 cm^2. BUT it asks for an answer written in SQUARE METRES so you have to change 450cm to metres making it 4.5 metres x 4.5 metres = 20.25 SO THE REAL ANSWER IS 20.25 M^2
