M∠LMJ = 162°; m∠JMI = 18°If ∠KMJ and ∠JMI are complementary angles, then what is the measure of ∠KMJ

Answers

Answer:

m∠KMJ = 72°

Step-by-step explanation:

Since, ∠KMJ and ∠JMI are complementary angles.

Therefore,

m∠KMJ + m∠JMI= 90°

m∠KMJ + 18° = 90°

m∠KMJ = 90° - 18°

m∠KMJ = 72°

Answer:

It's 72 degrees

Graph this function y-2=-(x+5)

Answers

Going to put your function in slope-intercept form for the sake of easier input into Desmos.

y - 2 = - (x + 5)
y - 2 = - x - 5
y = - x - 5 + 2
y = - x - 3

Four fifth of a number is more than three fourth of the number by 4. Find the number

Answers

Let the unknown number be x then given,

(4/5)x - (3/4)x = 4

(16x - 15x)/20 = 4

x/20 = 4

x=80

Let the number be n.

Four fifths of the number is 4n/5.

Three fourths of the number is 3n/4.

Four fifths of a number is more than three fourths of the number by 4.

4n/5 = 3n/4 + 4

20 * 4n/5 = 20 * 3n/4 + 20 * 4

16n = 15n + 80

n = 80

Let's check.

4/5 of 80 = 4/5 * 80 = 64

3/4 of 80 = 3/4 * 80 = 60

64 is indeed 4 more than 60 showing that 4/5 of 80 is 4 more than 3/4 of 80, so 80 is correct.

Answer: 80
