Answer:
57 °
Step-by-step explanation:
Complementary angles = 90 °
Since, Your angle don't have ∠ [ ] Then Let let "C" and "y"
Thurs, C = 12x- 3 and y = 7x - 2
It is given that angles r and s are complementary angles. Two angles are complementary if they add up to 90 degrees. This means the sum of measures of angle r and angle s must be 90 degrees. So,
c + y = 90
12x - 3 + 7x - 2 = 90
19x - 5 = 90
19x = 95
x = 95/19
x = 5
Using the value of x in expression or r, we get:
c = 12x - 3 = 12(5) - 3 = 60 -3 = 57 degrees.
So measure of angle c is 57 degrees.
Hence, the ∠ is 57 °

Answer:

Step-by-step explanation:
we know that
An isosceles triangle has two equal sides and two equal interior angles
In this problem
Triangle CDE is an isosceles triangle
because
EC ≅ DE
therefore
----> equation A
Remember that
The sum of the interior angles in any triangle must be equal to 180 degrees
so
----> equation B
---> equation C
substitute equation A and equation C in equation B

Answer:
Period=6
Step-by-step explanation:
Given:
t=1cos(1.05h)+37
Using acos(bx-c)+d to find the period of the given function
amplitude= a
period= 2π/Bb
phase shift=c (positive is to the left)
vertical shift=d
comparing with t=1cos(1.05h)+37, we get
a=1
b=1.05
c=0
d=37
period= 2π/b
=2π/1.05
=5.983
=6
Period of function is 6, after every 6 hours the refrigerator sensor will reach its maximum temperature and the cycle will move towards reducing temperature i.e it'll reach the minimum temperature then again the cycle will move upwards raising the temperature to maximum and so one period will be completed!
