Answer:
Step-by-step explanation:
3² + x² = 7²
x² = 7²-3² = 40
x = √40 = 2√10

An Isoceles Triangle has base 6cm long and the opposite angle to the base is 50 degrees l. What is the size of the other angle?
Answer:
65°
Step-by-step explanation:
From the question,
The base angle of an isoceles triangle are equal.
Let the value of the base angles = x°
Sum of angle in a triangle = 180°
⇒ x°+x°+50° = 180°
⇒ 2x°+50° = 180°
⇒ 2x° = 180°-50°
⇒ 2x° = 130°
⇒ 2x°/2 = 130/2
⇒ x° = 65°.
Hence, the size of the other angles is 65°

Consider the line y = 7x-5.
What is the slope of a line parallel to this line?
What is the slope of a line perpendicular to this line?
Answer:
[tex]\boxed {\sf Parallel: 7 }[/tex]
[tex]\boxed {\sf Perpendicular: -\frac{1}{7}}}[/tex]
Step-by-step explanation:
First, identify the slope.
We are given the line y=7x-5.
This is in slope intercept form or y=mx+b where m is the slope and b is the y-intercept. So, the coefficient to x, or 7 in this case, is the slope.
m=5Now, find the parallel and perpendicular slopes.
1. Parallel Slope
Parallel lines never intersect, so they have the same slope. A parallel line has a slope of 7.
2. Perpendicular Slope
Perpendicular slopes intersect to form right angles. They have negative reciprocal slopes.
Negate the slope: 7⇒ -7 Find the Reciprocal (flip the numerator and denominator: -7/1 ⇒ -1/7A parallel line has a slope of 7 and a perpendicular line has a slope of -1/7.
Answer:
I'll help
Step-by-step explanation:
Parallel lines have the same slope so it will be 7.
And perpendicular lines if you multiply them together they have to add up to -1,
So 7 you change it to its opposite which is 1 over 7 and yeah just
can you guys help me with this equation plzzzzzz
Answer:
b = 1/3
Step-by-step explanation:
Here, we want to solve for the value of b
From the question, we have that;
4^(3b-3) = 1/16
4^(3b-3) = 16^-1
4^(3b-3) = 4^2(-1)
4^(3b-3) = 4^-2
Since base are equal, equate the powers
3b - 3 = -2
3b = -2 + 3
3b = 1
b = 1/3

Find the leg of an isosceles right triangle when the hypotenuse measures 8
Answer:
4[tex]\sqrt{2}[/tex]
Step-by-step explanation:
ratio of leg to hypotenuse in a 45-45-90° triangle is 1 : [tex]\sqrt{2}[/tex]
we can use this proportion to solve the problem:
let 'x' = leg
x/8 = 1/[tex]\sqrt{2}[/tex]
cross-multiply:
[tex]\sqrt{2}[/tex] x = 8
x = 8 / [tex]\sqrt{2}[/tex]
if you multiply top and bottom by [tex]\sqrt{2}[/tex] you will get 4[tex]\sqrt{2}[/tex]
4 times (12-8) + 2^3. (2 to the 3rd power)
Answer:
It's 48. Heres why:
Step-by-step explanation:
Our equation, I believe, is 4[(12-8) + 2³]. We can do the operations in the parenthesis:
4[(4)+8] (12-8 = 4, and 2³ is 8). If we add 4 + 8, we get 12. Multiply 12 by 4, we get 48.
Is the given value a solution of the inequality?
z + 2> -4; z+ -8

what formula would you use to find the area of this figure?
Step-by-step explanation:
Find the area of a square or rectangle by multiplying the length times the width. This formula looks like l*w. If the length is 5 and the width is 2, the area is 10 square units. Calculate the area of a four-sided shape that is not a rectangle by multiplying the base (one of the sides) by the height.

* A helicopter's altitude changes by – 28 ft in 3 s.
What is the average change in the helicopter's altitude
each second? Show your work.
Answer:
-9.33 ft per second
Step-by-step explanation:
To calculate this, you just have to divide -28 by 3. When doing this, it will give the change per second or for every 1 second.
-28/3 = -9.33
Therefore, the average change in the helicopter's altitude each second is -9.33 ft.

11 with Exponent P 4
helpp please! i don't understand this
Answer:
Step-by-step explanation:
Remark
This is actually a six sided figure. That really doesn't matter, but it's interesting to observe. It goes a long way to explaining what is going on. The trick to exterior angles is that as long as the figure is convex ( a closed figure whose lines do not cross), the exterior angles add to 360.
Once you know that, then you know that this figure must have 6 exterior angles and no matter how they are made, their total is 360.
Equation
n + n + n + n + 90 + 90 = 360 Combine like terms.
Solution
4n + 180 = 360 Subtract 180
4n = 360 - 180
4n = 180 Divide both sides by 4
4n/4 = 180/4
n = 45

16 What value could you put in place of the x to make it a function? * (8, 7) (7,-6) (-4,5) (x, 9)
a) 8
b) 7
c) 9
d) -4
Answer:
(c) 9
Step-by-step explanation:
You can't have a repeated x-value in a function.
8 is taken by (8, 7)
7 is taken by (7,-6)
-4 is taken by (-4, 5)
9 is the only number that is not taken by any other point yet.
Remember that for a relationship to be a function it can't have repeated x-values. However, it doesn't matter to have the same x and y values!

Okay, so the formula for a trapezoid is A= ½ (b1+b2) h
14= b1
8= b2
Add them... You get 22. Multiply that by the height, which is 4. You should get 88. Then divide by 2. You should get 44.
