An angle measures 9.4° more than the measure of its complementary angle. What is the measure of each angle?

Answers

Answer:

x = one angle

90 - x = complementary angle {complementary angles add up to 90�}

x = 90 - x + 86 {one angle is 86� more than its complementary angle}

x = -x + 176 {combined like terms on right}

2x = 176 {added x to each side}

x = 88 {divided each side by 2}

90 - x = 2 {substituted 88, in for x, into 90 - x}

one angle is 88�

the complementary angle is 2�

What is distance formula?

The distance formula is a mathematical formula that is used to compute the distance between two points in a coordinate plane.

This formula is derived from the Pythagorean theorem, which states that the square of the length of the hypotenuse in a right triangle equals the sum of the squares of the lengths of the other two sides.

We can use the distance formula to find the length of AB:

[tex]d = \sqrt{ ((x2 - x1)^2 + (y2 - y1)^2)}[/tex]

Where (x1, y1) = (-4, 1) and (x2, y2) = (3, -1)

d = sqrt([tex](3 - (-4))^2 + (-1 - 1)^2[/tex])

= sqrt([tex]7^2 + (-2)^2[/tex])

= sqrt(49 + 4)

= sqrt(53)

≈ 7.3 (rounded to one decimal place)

Therefore, the length of AB is approximately 7.3 units.

if (a+b)+(a-b)i=7+2 find a and b​

Answers

Answer:

a = 4.5

b = 2.5

Step-by-step explanation:

The question is incomplete.

Complete question

If (a+b)+(a-b)i=7+2i find a and b

Compare the terms on both sides

a+b = 7

a-b = 2

Add both equations

a+a = 7+2

2a = 9

a = 9/2

a = 4.5

Recall:.

a+b = 7

4.5+b = 7

b = 7-4.5

b = 2.5
