A. m∠ADB = (7x + 27)° Find x .

Mathematics
1 answer:
Helen [10]3 years ago
8 0

Answer:

x = 9

y = 12

Step-by-step explanation:

✔️m<ADB = 90°

7x + 27 = 90

7x = 90 - 27

7x = 63

Divide both sides by 7

x = 9

✔️BC = 2(BD)

3y - 7 = 2(y + 3)

3y - 7 = 2y + 6

Collect like terms

3y - 2y = 7 + 6

y = 12

How do you do this? <br> Find M
Luden [163]

Answer:

Step-by-step explanation:

Let angle ABZ be angle 1 and angle ZBC be angle 2.

Angle 1 = 85 degree

Angle 2 = 6x + 9

measure of angle ABC = 24x+4

Angle 2 = ABC - 85

6x + 9 = 24x + 4 - 85

6x - 24x = 4 - 85 - 9

-18x = -90

x = -90/-18 = 90/18 =

x = 5

Therefore the measure of angle 2 = 6*5 + 9 = 30+9 = 39 degree

Therefore the measure of angle ZBC = 39 degree

Hope you understand

What is (2m+5) to the second power =0
drek231 [11]
I dont get the question so im going to show you both solutions
if you’re asking for (2m+5)²=0 then
(2m+5)²=0 /√
2m+5=0
m=-5/2

if you’re asking only for (2m+5)² then
4m²+20m+25

Manchu has drawn a
timama [110]

Answer:

Height of each triangle: 14cm

Area of each triangle: 168cm²

Step-by-step explanation:

So we know that the base of the area is 24. Lets find the height.

336 ÷ 24 = 14

If he makes two triangles out of the rectangle that just means he cuts it in half.

To find the area of one triangle lets do:

336 ÷ 2 = 168

Let's double check our answer:

(14 × 24) ÷ 2 = 168

Seems great!

Consider the function f (x) = x2.
klio [65]

Answer: The graph is shifted 2 units to the right.

Step-by-step explanation:

Given a function f(x), we know that one transformation rule is:

If f(x-k) then the function is shifted "k" units to the right.

 Therefore, for the function f(x)=x^{2}, when we subtract 2 from the input, then we get the function g(x) in the form:

 g(x)=(x-2)^{2}

We can conclude that subtracting 2 from the input of the function f(x)=x^{2}, then the graph is shifted 2 units to the right.
