Hello from MrBillDoesMath!

Answer:

x = 31


Discussion:

angle A + angle C + angle B = 180              (180 degrees in a triangle)

angle A + 57           +  61        = 180 =>         (substitution)

angle A + 118 = 180 =>

angle A = 180 -118 = 62


By the congruence statement, angle A = angle D = 2x so

62 = 2x =>

x = 31



Thank you,

MrB

Determine the value of x.​
Westkost [7]

Answer:

x = 4.59

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

tan theta = opp / adj

tan 74 = 16/ x

x tan 74 = 16

x = 16/ tan 74

x=4.58792

From delta math:<br> Subtract -2x^2 + 3x - 9 from 8x^2 + 10x - 10
Leto [7]

Answer:

10x^2 + 7x - 1

Step-by-step explanation:

Step 1: Build the expression in numerical form.

  • (8x^2 +10x - 10) - (-2x^2 + 3x - 9)

Step 2: Distribute the negative sign.

  • 8x^2 +10x -10 + (-1)(-2x^2) + (-1)(3x) + (-1)(-9)
  • 8x^2 + 10x - 10 + 2x^2 + (-3x) + 9  

Step 3: Combine like terms.

  • (8x^2 +2x^2) + (10x -3x) + (-10+9)
  • 10x^2 +7x -1

Therefore, the answer is 10x^2 + 7x -1.

You deposit $2200 into three separate bank accounts that each pay 3% annual interest. How much interest does each account earn a
Keith_Richards [23]
This can be solve using the formula:
F = P ( 1 + i)^n
where F is the money after n years
P is the initial amount of money
i is the annual interest rate
n is the time in years
since you deposit in 3 accounts P = 2200/3
F = ( 2200 / 3) ( 1 + 0.03)^6
F = $ 875.64 is the money each account earned after 6 years
