Answer:

The value of BC is 14.5 cm .

Step-by-step explanation:

Now by using the trignometric identity .

sin\theta = \frac{Perpendicular}{Hypotenuse}

As given

\theta = 65^{\circ}

Perpendicular = BC = x

Hypotenuse = AB = 16 cm

sin\theta = \frac{Perpendicular}{Hypotenuse}

sin\ 65^{\circ} = \frac{x}{AB}

0.9063\ (Approx) = \frac{x}{16}

x = 0.9063 × 16

x = 14.5 cm (Approx)

x = BC = 14.5 cm

Therefore the value of BC is 14.5 cm .

Find the measures of two complementary angles, ÐA and ÐB, if mÐA = (7x + 4)° and mÐB = (4x + 9)°. Measure of angle A = ... Measu
Westkost [7]

Answer:

The measure of angle A is 53 degrees

The measure of angle B is 37 degrees

Step-by-step explanation:

Here in this question, we are interested in calculating the measure of the two angle.

When how angles are complementary, it means the sum of both equals 90 degrees

mathematically ;

(7x + 4) + (4x + 9) = 90

7x + 4x + 4 + 9 = 90

11x + 13 = 90

11x = 90-13

11x = 77

x = 77/11 = 7

The measure of angle A = 7x + 4 = 7(7) + 4 = 49 + 4 = 53 degrees

The measure of B = 4x + 9 = 4(7) + 9 = 28 + 9 = 37 degrees

Snowcat [4.5K]
A. Find 10% of $20, which is $2. Then subtract the sale 20-2, which is $18
B. Since you know the price without taxes is $18, you have to multiply 8.5% of 18, which is $1.53. $18.00 + $1.53= $19.53

So the answer is $19.53
