Answer:
Angle I = 90 degrees
Angle J = 61 degrees
Angle K = 29 degrees
Step-by-step explanation:
Angle I is given
We know that the angles in all triangles add up to 180. Since we are given that angle I is equal to 90 degrees, we now know that angle J + angle K = 90 degrees:
(5x+26) + (2x+15) = 90
Solve for X:
7x + 41 = 90
7x = 49
x = 7
Angle J = (5x + 26) = (5(7) + 26) = 61
Angle K = (2x + 15) = (2(7) + 15) = 29
Checking your work: 61 + 29 = 90
Answer:
an=−4n+12
A sub n is equal to negative 4 n plus 12,
Step-by-step explanation:
Answer:
1. y=7.2
2. x=18
Step-by-step explanation:
1. Triangles CMN and CBA are similar triangles (by AAA postulate). Similar triangles have proportional corresponding sides, so
2. GK is angle G bisector. Use angle bisector's property:
Answer:
y = -3x + 14
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
Step 1: Write point-slope form
y - 2 = -3(x - 4)
Step 2: Solve into slope-intercept form
- Distribute -3: y - 2 = -3x + 12
- Add 2 to both sides: y = -3x + 14
