Answer:
Since x is an exponent, y = 15 × 8ˣ represents an exponential function.
Answer:
103⁰
Step-by-step explanation:
straight line= 180⁰
180⁰-77 = 103⁰
Answer:
24
Step-by-step explanation:
since c=4 and d=48, we can re-write this equation
48-6 x 4
48 - 24
24
The value of x can be found using the sine function.
sin 30 = x/8
8 (sin 30) = x
4 = x
Answer:
x = 21, m∠A = 23°, the measure of angle in the right = 67°
Step-by-step explanation:
The angles of a triangle sum up to 180°.
Right angles equals to 90°.
Thus, (2x - 19)° + (3x + 4)° + 90° = 180°
=> 5x + 75 = 180
=> 5x = 105
=> x = 21
m∠A=> 2(21) -19 = 23°
the measure of angle in the right=> 3(21) + 4 = 67°
