Answer for 2:
x = 28
Step-by-step explanation:
Since the overall angle is 90°, and we already have 33, we subtract 33 from 90
90 - 33 = 57
So we have to fill in the other 57°
2(28) = 56
56 + 1 = 57
So the answer is x = 28
Hello!
To find the value of b, we need to use the Law of Sines. The law states,
sin A / a = sin B / b = sin C / c.
We are given these values: sin A = 55 degrees, side a = 8 cm, sin C = 82 degrees.
Since angle B is not given, we have to find it ourselves. We can find the measure of angle B by subtracting both the given angle values from 180 degrees because every triangle is equal to 180 degrees.
180 - 55 - 82 = 43 | The measure of sin B = 43 degrees.
sin (55) / 8 = sin (43) / b (multiply both sides by b)
0.10239... · b = 0.68199... (divide both sides by 0.10239...)
c = 6.6607...
The measure of side b is equal to about 6.7 centimeters.
So, y-intercept is (0,3) and x-intercept is (3/7,0)
Step-by-step explanation:
We are given:
We need to find y-intercept and x-intercept
Finding y-intercept
To find y-intercept we put x =0
Solving:
So, y-intercept is (0,3)
Finding x-intercept
To find x-intercept we put y =0
Solving:
So, x-intercept is (3/7,0)
So, y-intercept is (0,3) and x-intercept is (3/7,0)

Answer:
A 7/25
Step-by-step explanation:
The cosine of an angle is equal to the sine of its complement. In a right triangle, angle A is the complement of angle B. So, ...
cos(A) = sin(B)
cos(A) = 7/25
