Make a triangle with an opposite side of 4 and adjacent side of 3 (hypotenuse is 5). You can now work out all trig functions for that angle. including sin(x)

Use the double angle formula to find sin(2x)

Angle A and Angle B are complementary angles. If angle B is five degrees more than four times angle A, find the measure of each

kupik [55]

Answer:

Angle A = 17°, Angle B = 73°

Step-by-step explanation:

Angle A & Angle B are complementary angles (given) so they will form 90°.

Let's take,

Angle A = x

Angle B = 4x +5 (angle B is five degrees more than four times angle A)

Measure of each angle=?

Angle A + Angle B = 90°

x + 4x + 5 = 90

5x + 5 = 90

5x = 90 - 5

5x = 85

x = 85 ÷ 5

x = 17°

Angle A = x = 17°

Angle B = 4x + 5 = 4(17) + 5 = 68 + 5 = 73°

1. Truncate the following numbers to the unit: a) 25 b) 76 c) 10

deff fn [24]

Answer:

1 Truncation

Truncation is a method of approximating numbers. It is easier than rounding, but does not always give the best approximation to the original number. Truncation is used in computing when division is done with integers and the answer must be an integer.
