The answer is True.
One radian is the central angle that subtends an arc length of one radius (s = r). Since all circles are similar, one radian is the same value for all circles. The arc measure of the central angle of an entire circle is 360º and the radian measure of the central angle of an entire circle = 2π.
Greatest common factor (GCF) of 7 and 15 is 1. We will now calculate the prime factors of 7 and 15, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 7 and 15.
B looks like the most probable choice because x is sitting between -2 and y is on 1.
Answer:
D)
BC = 9; m∠A = 36.9°; m∠B = 53.1°; m∠C = 90°
Step-by-step explanation:
15²-12² = 9²
BC = 9
sin B = 12/15 = 0.8
∠B = 53.1°
m<1 = 59°
m<2 = 90° - 59° = 31°
m<3 = 59°
m<4 = 31°
m<5 = 31°
m<6 = 59°
m<7 = 180° - (31° + 31°) = 118°
m<8 = 180° - 118°= 62°
m<9 = m<8 = 62°
m<10 = m<7 = 118°
m<11 = 31°
