Answer:
so involved triangles we know that one angle is 90° because of the right angle sign and you know that two x two interior angles add up to 180 angle so 90 degrees we will name the unknown angle x + x is equals to 127 degrees x is equals to 37 degrees so we have two angles are both of the triangles that is 90 degrees and 37 degrees 37 degrees is on the upper part of the triangle so it'll be 37° + 37° to get 74 degrees and the angle that you're looking for is a reflex angle so it'll be 360 degrees - 74 degrees so they think the answer is 286 degrees
Answer:
A= 3215.36 in²
C= 100.48 in
Step-by-step explanation:
A= πr²
A=3.14(<u>32²</u>)
A= <u>3.14(1024)</u>
A= 3215.36 in²
C= πd
C= <u>3.14(32)</u>
C= 100.48 in
First, fint the roots of the equation 
1.
2. You can see that this equation has two different real roots. Note that you can make this statement without finding roots, only knowing the value of discriminant: since D=81>0, then the equation has two different real roots.
The answer to this question is Letter B.
