Abcd is a rhombus where m∠dac=4x+9 and m∠dab=11x−3

We are given

ABCD is a rhombus

so, firstly , we need to draw diagram

we can see that

diagonal bisects angle

so,

m∠DAB=2*m∠DAC

now, we can plug values

now, we can solve for x

subtract both sides by 8x

Divide both sides by 3

we get

...............Answer

angle q= 92 degree

step-by-step explanation:

the solution is in the picture

when a quadrilateral is inscribed in a circle, the opposite angles are supplement to each other. in other words, the sum of the 2 angle is 180 degree

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.
