Answer:
7 years
Step-by-step explanation:
Suri's age=17 years
Her cousin's age =c
Suri's age is 4 less than 3 times her cousin's age
4 less than 3 times her cousin's age means subtract 4 from 3 times her cousin's age
17=3c - 4
Find c which is her cousin's age
Add 4 to both sides
17+4=3c - 4 + 4
17+4=3c
21=3c
Divide both sides by 3
21/3=3c/3
7=c
Therefore,
C= 7
Her cousin's age = 7 years
Answer:
4th option
Step-by-step explanation:
The chord- chord angle 67.5° is half the sum of the arcs intercepted by the angle and its vertical angle, that is
67.5 = 
(x + 90)
Answer:
Adjacent length = √(50) m
Pythagorean theorem:
a^2 + b^2 = c^2
a = √(50) m
b = √(50) m
c^2 = √(50)^2 + √(50)^2
c^2 = 50 + 50
c^2 = 100
c = 10 m
Diagonal = 10 m
Answer:
C. 22 M
