Answer:
212586955997.2
Step-by-step explanation:
90^5x36-(35+60)÷25+57^4
36x90^5-95÷25+57^4
36x90^5-3.8+57^4
Solution
36x90^-3.8+57^4
Alternate form
212586955997.2
Marcus should have substituted -10for b, not 10
Marcus should have subtracted 4(1)(25) in the square root
This equation, when solved correctly, only has one real number solution
So A, C, D
12 hours
to calculate time divide distance by average speed
time = = 12.5 = 12
Answer:
0° to 90°: reference angle = angle ,
90° to 180°: reference angle = 180° - angle ,
180° to 270°: reference angle = angle - 180° ,
270° to 360°: reference angle = 360° - angle .
Step-by-step explanation:
Definition of Reference Angle: Let θ be a non-quadrantal angle in standard position. The reference angle of θ is the acute angle θR that the terminal side of θ makes with the x-axis. If θ is in QI, θR = θ If θ is in QII, θR = 180° – θ or π – θ If θ is in QIII, θR = θ – 180° or θ – πThe reference angle of 240° is 60°. To find the reference angle of a given angle, A, with measure x°, we start by adding or subtracting. You can see that the terminal side of the 135° angle and the x-axis form a 45° angle (this is because the two angles must add up to 180°). This 45° angle, shown in red, is the reference angle for 135°.
Answer:
D. 76
Step-by-step explanation:
a = 90°
a + b + 14 = 180°
90 + b + 14 = 180°
b = 180 - (90 + 14 )
b = 76°
