Answer:

x = 15

Step-by-step explanation:

We are told that a right angle is divided into two parts

A right angle = 90°

Part A = 30°

Part B = 4x

Hence:

30° + 4x = 90°

Collect like terms

4x = 90° - 30°

4x = 60°

4x = 60/4

x = 15

Therefore, the value of x = 15

A) 45 because 1350 divide by 30 equals 45. So 45 dollars u can afford

B) 1350 because 45 x 30 = 1350

C) 7% because it’s 7% to begin with

6(x+7) + (x+3)<br> 7x + 10<br> 7x + 45<br> 2x = 21<br> 42 + 45x

fenix001 [56]

7x + 45
(6x +42) + (x +3)= 7x + 45

What is true about △ABC? Select three options

rjkz [21]

Answer:

A) AB ⊥ AC

B) The triangle is a right triangle.

C) The triangle is an isosceles triangle

Step-by-step explanation:

we know that

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

step 1

Find the distance AB

we have

$A(-1,3), B(-5,-1)$

substitute in the formula

$d=\sqrt{(-1-3)^{2}+(-5+1)^{2}}$

$d=\sqrt{(-4)^{2}+(-4)^{2}}$

$d_A_B=\sqrt{32}\ units$

step 2

Find the distance BC

we have

$B(-5,-1),C(3,-1)$

substitute in the formula

$d=\sqrt{(-1+1)^{2}+(3+5)^{2}}$

$d=\sqrt{(0)^{2}+(8)^{2}}$

$d_B_C=8\ units$

step 3

Find the distance AC

we have

$A(-1,3),C(3,-1)$

substitute in the formula

$d=\sqrt{(-1-3)^{2}+(3+1)^{2}}$

$d=\sqrt{(-4)^{2}+(4)^{2}}$

$d_A_C=\sqrt{32}\ units$

step 4

Compare the length sides of triangle

$d_A_B=\sqrt{32}\ units$

$d_B_C=8\ units$

$d_A_C=\sqrt{32}\ units$

therefore

The triangle ABC is an isosceles triangle, because has two equal sides

The triangle ABC is a right triangle because satisfy the Pythagoras theorem

$BC^2=AB^2+AC^2$

$8^2=(\sqrt{32})^2+(\sqrt{32})^2$

$64=32+32$

$64=64$ ----> is true (Is a right triangle)

AB ⊥ AC because in a right triangle the legs are perpendicular
