We are given a concave spherical mirror with the following dimensions:
Radius = 60 cm; D o = 30 cm
Height = 6 cm; h o = 6 cm
First, we need to know the focal length, f, of the object (this should be given). Then we can use the following formulas for calculation:
Assume f = 10 cm
1/ f = 1 /d o + 1 / d i
1 / 10 = 1 / 30 + 1 / d i
d i = 15 cm
Then, calculate for h i:
h i / h o = - d i / d o
h i / 6 = - 15 / 30
h i = - 3 cm
Therefore, the distance of the object from the mirror is 3 centimeters. The negative sign means it is "inverted".
Answer:
x=16
(5x + 27)° =5(16)+27=80+27=107
(5x – 7)º= 5(16)-7=80-7=73
Step-by-step explanation
supplementary angle=180
(5x + 27)° + (5x – 7)º=180
5x+27+5x-7=180
10x+20=180
10x=180-20
10x=160
x=160/10
x=16
(5x + 27)° =5(16)+27=80+27=107
(5x – 7)º= 5(16)-7=80-7=73
107+73=180
