What is the value of x to the nearest tenth?

The correct answer is (C) 8.8

Step-by-step explanation: The given triangle has two sides and two angles given. However it is not a right angled triangle. In order to calculate an unknown side or angle in questions such as this, we shall apply the sine rule, which states;

a/SinA = b/SinB = c/SinC

Where the reference angle is that facing the line (that is, SinA is the angle facing line a, etc).

To calculate x, we shall use angle 28 as the reference angle. We have also been given line 8.2, and the angle facing it is derived as

180 - (28 + 126)

= 180 - 154

= 26

If the angle facing line 8.2 is 26, then the sine rule can be applied as follows;

x/Sin28 = 8.2/Sin26

By cross multiplication we now have

x (Sin26) = 8.2 (Sin28)

x = [8.2 (Sin28)]/Sin26

x = (8.2 x0.4695)/0.4384

x = 8.7817

Approximately x = 8.8 (to the nearest tenth)

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.

a mantle plume is an upwelling of abnormally hot rock within the earth's mantle. as the heads of mantle plumes can partly melt when they reach shallow depths, they are thought to be the cause of volcanic centers known as hotspots and probably also to have caused flood basalts.
