Find the value of x to the nearest tenth

Check the picture below.

make sure your calculator is in Degree mode.

The opposite side x is 7

Step-by-step explanation:

Step one

From the given expression in the picture

We can estimate x by applying the

SOH CAH TOA rule on the triangle

Since we have one side and one angle given

step two

From the given picture we have

We have θ and adjacent side given

Hence we need to apply

tan θ= opposite/adjacent =

Tan 35°=x/10

Step three

From 4 figure table or calculator

tan 35° is 0.7

0.7=x/10

x=0.7*10

x= 7

i’ll just s take the points thxs

(5x-1)^2= (5x)^2-2(5x)×1+(1)^2=25x^2-10x+1
