63 + a = 90; subtract 63 from both sides of the equation.
Taya2010 [7]2 years ago

Answer:

Option B, 63 + a = 90; subtract 63 from both sides of the equation

Step-by-step explanation:

When the sum of two angles is equal to 90 degrees, they are called complementary angles.

Here, we  know the one angle measure is 63°

Let's consider unknown angle as a.

63 °+ a = 90°

63 °+ a -63° = 90° - 63° ( subtract 63 from both sides of the equation)

a = 90° - 63°

a = 27°

Any idea ? I need help
trasher [3.6K]
Use the Pythagorean Theorem:
a^2 + b^2= c^2

a= one side= 68 mi
b= second side= 80 mi
c= hypotenuse= Greenville to Columbia mi


a^2 + b^2= c^2

68^2 + 80^2= c^2
square each number

4,624 + 6,400= c^2

11,024= c^2
take square root of both sides

104.995 mi= c


ANSWER: The distance from Greenville to Columbia is 104.995 miles (rounded to 105 miles).

Hope this helps! :)

What is the distance between the point (−10, −2)(−10, −2) and the point (−4, −2)(−4, −2) ?
Gnoma [55]
In this case:  x 1 = - 10,  y 1 = - 2;
x 2 = - 4 ,  y 2 = - 2
The distance between the points :
d =  \sqrt{(x 2 - x 1 ) ^{2} + ( y 2 - y 1 ) ^{2} } = \\  =\sqrt{(-4+10) ^{2} +(-2+2) ^{2} } = \\ = \sqrt{6 ^{2}+0 ^{2}  } = \sqrt{36}= 6
Answer: d = 6

How do I find the slope of the line through (–9, –10) and (–2, –5)?
storchak [24]
Answer:
slope of line is 5/7

Explanation:
The slope of the line can be calculated using the following rule:
slope = \frac{y2-y1}{x2-x1}

The given points are:
(-9,-10) which represent (x1,y1)
(-2,-5) which represent (x2,y2)

Substitute with the points in the above equation to get the slope as follows:
slope = \frac{-5-(-10)}{-2-(-9)} = 5/7

Hope this helps :)
