Answer:
8
Step-by-step explanation:
10+8-3+5-12=
Answer:
m = -3
Step-by-step explanation:
Divide both sides by 4.
m + 2 = -1
Subtract 2 from both sides.
m = -3
Answer:
114,570,685.26
Step-by-step explanation:
100,236,820 x 14.3% = 14,333,865.26
100,236,820 + 14,333,865.26 = 114,570,685.26
Answer:
B
Step-by-step explanation:
The 115° angle is adjacent to both unknown angles in the triangles, thus
unknown angles = 180° - 115° = 65°
The sum of the 3 angles in a triangle = 180°, thus
∠ 1 = 180° - (65 + 80)° = 180° - 145° = 35°
∠ 2 = 180° - (65 + 85)° = 180° - 150° = 30°
Answer:
Step-by-step explanation:
Suppose triangle CAD with A = 60^0 and triangle ABE with B = 60^0. They are similar (the order matter, don't change the order)
We have CD = AE and AD = BE , AC = AB (radius)
in triangle CAD, cos A = cos (60) = AD/ AC
in triangle ABE, sin A = sin (30) = BE/AB
We have denominators are equal (both are radius of the circle) and numerator are equal, that gives cos (60) = sin (30)
