Answer: a = 45°
Step-by-step explanation:
The measure of∠PSR is given: 90°
Given PS = RS, this is an isosceles triangle. so measure of ∠SPR, labeled "a" is equal to the measure of ∠SPR.
The total of all angles in a triangle is 180. So subtract 90, then divide by 2.
180-90 = 90
90/2 = 45
a = 45°
<em>If "b" is supposed to be the measure of ∠SRQ, that is 15° The larger triangle is equilateral; all the angles are 60°. 60 - 45 = 15</em>
If you divide 64 by 4 then u get 16 so r is 16
Im not sure, you didn't put a question
If we do 9 * 4 we can see that that is 36. So the board is 36 inches.
Answer:
The order of operations is Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction.
Step-by-step explanation:
The order of operations is PEMDAS.
P: Parenthesis
E: Exponents
M: Multiplication
D: Division
A: Addition
S: Subtraction
An easy way to remember PEMDAS is, please excuse my dear aunt sally.
Hope this helps!
If not, I am sorry.
