Okay this is what i got it might be wrong but i did it and then looked it up to make sure i was right & it showed the same answer!!
3.55 * 1.6= 5.68!!
Answer:
57.5°
Step-by-step explanation:
For triangle ABC C = 90 Side AC = 13.5 Side BC = 8.6 Find the measure of angle B
We solve using the Trigonometric function of Tangent
tan θ = Opposite/Adjacent
θ = Angle B
Opposite = Side AC 13.5
Adjacent = Side BC = 8.6
Hence:
tan θ = 13.5/8.6
θ = arc tan (13.5/8.6)
θ = 57.501354056°
Approximately = 57.5°
Therefore, Angle B = 57.5°
Answer:
x = 88
The measurement of the other unknown angle is = 44°
Step-by-step explanation:
The sum of interior angles in a triangle is equal to 180°
48 + x + x - 44 = 180 add like terms
4 + 2x = 180 subtract 4 from both sides
2x = 176 divide both sides by 2
x = 88
Now to find the measure of two other angles we replace x with 88
Answer:
b= -3

Answer:
0.9056
Step-by-step explanation:
We are given;
Number of students enrolled in both General Chemistry and Calculus I = 540 students
Number of students who received an A in general chemistry = 51 students
Number of students who received an A in calculus = 59 students
Number of students who received an A in both general chemistry and calculus = 30 students
Now, we want to find the probability that a randomly chosen student did not receive an A in general chemistry.
So, first of all let's calculate number of students who didn't receive an A in chemistry.
So,
No without A in chemistry = 540 - 51 = 489 students
So, probability that a randomly chosen student did not receive an A in general chemistry = 489/540 = 0.9056
