Find the value of x. Round to the nearest tenth.

thank you in advance for the help!

Step-by-step explanation:

YOU HAVE TO USE THE PYTHAGORAS THEORAM

x ≈ 3.1

Step-by-step explanation:

Using Pythagoras' identity in the right triangle with hypotenuse 2.1 and

legs 1.4 and x, thus

( x )² + 1.4² = 2.1², that is

x² + 1.96 = 4.41 ( subtract 1.96 from both sides )

x² = 2.45 ( multiply both sides by 4 )

x² = 9.8 ( take the square root of both sides )

x ≈ 3.1 ( to the nearest tenth )

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
