Answer:

m\angle I = 90\degree

m\angle J= 61\degree

m\angle K = 29\degree

Step-by-step explanation:

(5x + 26)° + (2x + 15)° = 90°

(5x + 26 + 2x + 15)° = 90°

(7x + 41)° = 90°

7x + 41 = 90

7x = 90 - 41

7x = 49

x = 49/7

x = 7

m \angle \: I= 90 \degree \\  \\ m \angle \: J=(5x + 26) \degree = (5 \times 7 + 26) \degree \\  \\ m \angle \: J =  (35+ 26) \degree \\  \\ m \angle \: J= 61\degree\\  \\ m \angle \: K=(2x + 15) \degree = (2 \times 7 + 15) \degree \\  \\ m \angle \: K =  (14+ 15) \degree \\  \\ m \angle \: K = 29\degree

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

Explain why 21i^2 is equivalent to -21
Citrus2011 [14]

Answer:

Step-by-step explanation:

The imaginary number 'i' is equal to the square root of -1. If you were to square the square root, they both cancel and you get -1.

21i^2=21(\sqrt{-1} )^2=21(-1)=-21
