I need help with this in 7th grade just started to learn this

99

Step-by-step explanation:

110% × 90 = 99

OR

110/100 × 90 (Simplify this)

11/10 × 90 (Divide 10 into 90 / Cross multiply)

11 × 9 = 99

110/100*90=x

11*9=x

99=x is your answer ☺️. If I'm right so,

Please mark me as brainliest. thanks!!!

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.

150.6

all i did was i multiplied 5.02 by 30
