The angle whose sine is 0.39581 is 23.31650126° (round it how you want).
To calculate this, you need to do the inverse sine of 0.39581.
Inverse sine looks like

, however, it is not the sine of the angle to the power of -1.
°C = (°F-32) ÷ 1.8
°C = (350-32) ÷ 1.8
°C = 318 ÷ 1.8 = 176.66 ≈ 177°C
Answer: C = 1.69
Step-by-step explanation:
E is proportional to √C
To remove proportionality, introduce a constant (k).
E = k × √C
From question,
E = 40 and C = 25
So,
40 = k ×√25
40 = k × 5
k = 8
Now,
C = ?
E = 10.4
k = 8
E = k × √C
10.4 = 8 × √C
10.4 / 8 = √C
( 10.4 / 8 ) ^ 2 = C
C = 1.69
Given the the two angles find the missing angle of P which is 30 degrees.
Since angle P and C are identical their sides are congruent.
The hypotenuse, the largest side is PC because it corresponds to angle T
Using Pythagorean Theorem
a^2 + b^2 = c^2
(PT)^2 + (CT)^2 = (PC)^2
Given that PT is 4 and knowing PT and CT are congruent we can rewrite this
(4)^2 + (4)^2 = (PC)^2
PC = rad(32)
