Answer:
-4
Step-by-step explanation:
Find the value of x in each diagram.
Answer:
4. 25 5. 80 6. 30
Step-by-step explanation:
All triangles add up to 180.
The triangle in #4 is right, so 90° + 65° = 155°
180° - 155° = 25°
x=25
#5.
50° + 50° = 100°
180° - 100° = 80°
x=80
In #4 the triangle is an equilateral, so all the angles will be equal. 2x + 2x + 2x = 180
6x = 180
x = 30
Step-by-step explanation:
The sum of interior angles in a triangle is equal to 180°
Two of the angle measures are given in each triangle so to find the third angle measurement we need to subtract the sum of two of the interior angles
4.
180 - (65 + 90) = x
180 - 155 = x
25 = x
5.
180 - (50+5) = x
180 - 100 = x
80 = x
For the 6th question all side lengths are equal so the angle measures also equal and 60 each
2x = 60
x = 30
SOLVE FOR X!!
(will mark brainliest)
Answer:
19
Step-by-step explanation:
Since it is a 90° angle we can say that 3x-15+2x+10 = 90.
3x-15+2x+10 = 90
5x-5=90
5x=95
x=19
By solving this we find that x is equal to 19.
Answer:
19
Step-by-step explanation:
3*19 = 57
57 - 15 = 42
2*19 = 38
38 + 10 = 48
48 + 42 = 90
(As this is a 90 degree angle)
SOLVE FOR X TO THE NEAREST TENTH
Answer:
x = 8.8
Step-by-step explanation:
First, you have to solve the side length for the smaller triangle.
[tex]c= \sqrt{ a^{2} +b^{2} }\\c= \sqrt{5^{2}+4^{2} } \\\\c=\sqrt{25+16} \\c=\sqrt{41} \\c= 6.4\\[/tex]
Now for the bigger square.
[tex]c= \sqrt{ a^{2} +b^{2} \\} \\c = \sqrt{6.4^{2} +6^{2} } \\c= \sqrt{40.96+36} \\c= \sqrt{ 76.96}\\c= 8.77\\[/tex]
Rounded to the nearest tenth = 8.8

Answer:
156.6 meters squared
Step-by-step explanation:
There are 3 triangles for the sides. The area for a triangle is one half base times height. So we are doing one half of 9 times 9. This is 40.5. Since there are 3 of them we can just multiply 40.5 times 3 to get 121.5. And now to solve for the base triangle, it is one half of 9 times 7.8. We get 35.1. Now add together 121.5 and 35.1. We get 156.6. Now since this is surface area it is meters squared.

Answer:
A = 81
Step-by-step explanation:
When there is a number above the other. You will need to multiply it.
There is a 4 so its 4 times.
-3 x -3 = 9
9 x -3 = -27
-27 x -3 = 81

major arc BRA is 3/2 the length of minor arc BSA. the length of major arc BRA is 6pi centimeters. what is the radius of the circle?
9514 1404 393
Answer:
5 cm
Step-by-step explanation:
The given arcs have the ratio ...
BRA : BSA = (3/2) : 1 = 3 : 2
Then BRA is 3/(3+2) = 0.6 of the total circumference of the circle.
0.6(2πr) = 6π . . . . . BRA is 6π long
r = 6π/(1.2π) . . . . . . divide by the coefficient of r
r = 5 . . . . centimeters
A cardboard box in the shape of a rectangular prism has the dimensions shown. Write a polynomial in standard form to represent the volume of the box.
Answer:
[tex]Volume = x^3 +3x^2 -16x +12[/tex]
Step-by-step explanation:
Given [missing from the question].
The dimensions are:
Length =(x + 6), Width = (x - 2) and Height = (x -1)
Required
Represent the volume as a polynomial
Volume is calculated as:
[tex]Volume = Length * Width * Height[/tex]
So:
[tex]Volume = (x + 6) * (x - 2) * (x - 1)[/tex]
Expand
[tex]Volume = (x + 6) * (x^2 -2x -x +2)[/tex]
[tex]Volume = (x + 6) * (x^2 -3x +2)[/tex]
Expand
[tex]Volume = x^3 -3x^2 +2x +6x^2-18x +12[/tex]
Collect like terms
[tex]Volume = x^3 -3x^2+6x^2 +2x -18x +12[/tex]
[tex]Volume = x^3 +3x^2 -16x +12[/tex]

the arrow always points to the smallest side
D) the opening of the arrow is always on the smallest side.
Answer:
C) the arrow always points to the smaller side
Step-by-step explanation:
if you struggle to remember think of it as a crocodile going for the highest amount of 'food', in this case the food is the number
Answer: C, the arrow always points to the smallest side.
Step-by-step explanation:
A way of remembering which way the '>' sign goes is to think of it as a crocodile mouth (the open bit) and the crocodile wants the most food (the biggest number).
