What is the value of x in the diagram? #3
A) 530
B) go
127°
349
C) 112
146°
D) 180°

option c is correct.

step-by-step explanation:

the rule regarding the sides of triangle is:

(length of longest side)^2 = square of sum of other two sides.

the sides given are:

6, 10 and 8.

applying the rule we will get:

(10)^2 = (6)^2 + (8)^2

100 = 36+64

100 = 100

so, her answer is incorrect.

no, she should have added 6^2 and 8^2 and compared that to 10^2.

so, option c is correct.

answer is c

step-by-step explanation:

a = π r² (\frac{x}{360} )

360a =   π r² x

\frac{360a}{\pi r^{2}}   = x

step-by-step explanation:

-7.8

step-by-step explanation:

3.5 + -7.8 = -4.3

3.5 + -7.4 = -3.9

3.5 + -7.1 = -3.6

3.5 + -1.2 = 2.3
