The question does not specify the condition that must satisfy the given angles. We assume they are the internal angles of a triangle.

Answer:

x = 10

Step-by-step explanation:

Internal Angles of a Triangle

The measure of the angles of a triangle are given as 48-x, 9x-38, and 90. Since the sum of the internal angles of a triangle is 180°:

48 - x + 9x - 38 + 90 = 180

Simplifying:

100 + 8x = 180

Subtracting 100:

8x = 180 - 100 = 80

x = 80/8

x = 10

The sum of 43 and z is equal to 72.98. Enter the equation that represents the description.

Irina-Kira [14]

sum is an answer to an addition problem, so we have to add 43 and z. z+43=72.98

Subtract 43 on both sides.

z=29.98

Find the sine and cosine of each angle as a fraction and as a decimal. Round to the nearest hundredth.

lawyer [7]

Answer:

1st triangle:

sin(C): 0.64, $\frac{16}{25}$

cos(C): 0.8, $\frac{4}{5}$

Second triangle:

sin(C): 0.75, $\frac{\sqrt{5} }{3}$

cos(C): 0.67, $\frac{2}{3}$

Step-by-step explanation:

Using SOH CAH TOA, we know that to find the sin of an angle, it's Opposite/Hypotenuse.

To find the cos of an angle, it's adjacent/hypotenuse.

In the 1st triangle:

The adjacent to C is 16, the hypotenuse is 25.

$\frac{16}{25} = 0.64$ is the sin of C.

The adjacent to C is 20, and the hypotenuse is 25.

$\frac{20}{25} = 0.8$ is the cos of C.

In the second triangle:

The opposite to C is $\sqrt{5}$ and the hypotenuse is 2.

$\frac{\sqrt{5} }{2} \approx0.75$ is the sin of C.

The adjacent to C is 2 and the hypotenuse is 3.

$\frac{2}{3} \approx 0.67$ is the cos of C.

Hope this helped!
