Answer:

D ∠U=106°

Step-by-step explanation:

∠TRS=∠RTU=31 (corresponding angles)

Since all angles in a triangle add up to 180:

∠TRS+∠RTS+∠RST=180

31+(4x-5)+(7x+22)=180

48+11x=180

11x=132

x=12

∠RST=7x+22=7(12)+22=84+22=106

∠RST=∠U (opposite angles in a rhombus are equal)

∠U=106°

Find the unit rate 6 and 2/5 revolutions in 2 and 2/3 in seconds
Makovka662 [10]

<u>Step 1</u>

Convert mixed fractions into fractions

6 2/5 = (6*5)+2) / 5 = 32/5

2 2/3 = (2*3)+2) / 3 = 8/3

<u>Step 2</u>

32/5 ÷ 8 / 3 ; where 32/5 is the 1st fraction and 8/3 is the 2nd fraction

<u>Step 2 (A)</u>

Get the reciprocal of the 2nd fraction:

From 8/3 to 3/8

<u>Step 2 (B)</u>

Multiply 1st fraction to the reciprocal of the 2nd fraction

32/5 * 3/8 = (32*3) / (5*8) = 96/40

<u>Step 2 (C)</u>

Simplify the fraction

96/40 divide by 4 will become 24/10

24/10 divide 2 will become 12/5. The simplest fraction of 96/40

The unit rate is 12/5 = 2 2/5 revolutions per second
