The diagonals of a rhombus bisect<span> each other at </span>right angles (90°) and in a triangle, the three interior angles always add to 180° ⇒

3x + 2 + 4x - 10 + 90 = 180
7x + 82 = 180
7x = 180 - 82
7x = 98
x = 98/7
x = 14

ASAP please help me I don’t not know how to find the Y intercept from two points

faltersainse [42]

They way to find the y-intercept from two points is to first find the slope, which can be derived from the formula $m=\frac{y_2-y_1}{x_2-x_1}$ .

Then, you can plug in one of the two points $(x_1,y_1)$ or $(x_2,y_2)$ into the formula y=mx+b to solve for b, which is your y-intercept.

6. Find the value of x in the triangle below.

Kobotan [32]

Answer:

The value of x is 21.

Step-by-step explanation:

Since this is a right angle triangle, you can apply Pythagoras theorem, side² + side² = hypo² :

(x + 3)² + 10² = (x + 5)²

x² + 6x + 9 + 100 = x² + 10x + 25

x² + 6x + 109 - x² - 10x - 25 = 0

-4x + 84 = 0

-4x = -84

4x = 84

x = 84 ÷ 4

x = 21 units
