Answer:

103°

Step-by-step explanation:

This is a cyclic quadrilateral (all vertices on the same circle)

Opposite angles are supplementary:

∠A + ∠C = 180°
∠B + ∠D = 180°

Find x:

x + 5 + x - 7 = 180°
2x - 2 = 180°
2x = 182°
x = 91°

Find D:

∠D = x - 14°
∠D = 91° - 14° = 77°

Find B:

∠B = 180° - 77° = 103°

If x+y = -10 and x-y = 2 what is the value of x

-BARSIC- [3]

Answer:

x = -4

Step-by-step explanation:

The solution to a "sum and difference" system of equations can be found by adding the equations together.

(x +y) +(x -y) = (-10) +(2)

2x = -8 . . . . . . simplify

x = -4 . . . . . . . divide by 2

Additional comment

y = -6, though this question did not ask that value.

5. AC bisects Angle BAD. Find the measure of angle BAC.

alukav5142 [94]

If AC bisects < BAD, it means it cuts it into 2 equal parts

so < BAC = < CAD

3x + 12 = 5x
12 = 5x - 3x
12 = 2x
12/2 = x
6 = x

< BAC = 3x + 12.......3(6) + 12 = 30 degrees <===

WILL GIVE BRAINLIEST Mr. and Mrs. Bailey hope to send their son to college in eleven years. How much money should they invest no

Ronch [10]

Mr. and Mrs. Bailey need to invest $2906.50 so as to send their son to college.

<h3>Compound interest</h3>

Compound interest is given by:

$A=P(1+\frac{r}{n})^{nt}$

where A is the amount after t years, P is initial amount, r is the rate and n is the times compounded per period

Given that n = 1, r = 9% = 0.09, A = $7500 t = 11. Hence:

$7500=P(1+\frac{0.09}{1} )^{1*11}\\\\P=\$2906.50$

Mr. and Mrs. Bailey need to invest $2906.50 so as to send their son to college.
