Area of a triangle
Side Angle Side (SAS) Method :
Given a triangle with two known sides a and b, and their included angle C, the area can be calculated as follows:
[tex]\displaystyle A=\frac{a.b.\sin(C)}{2}[/tex]
The triangle has sides of lengths a=7 and b=9 and their included angle is C=72°. Substituting:
[tex]\displaystyle A=\frac{7\cdot 9.\sin(72^\circ)}{2}[/tex]
A = 29.96

how do you solve 6-9(4p-3)= 2(6p+7)+3
Answer:
p= 1/3
=0.333
Step-by-step explanation:
Simplifying
6 + -9(4p + -3) = 2(6p + 7) + 3
Reorder the terms:
6 + -9(-3 + 4p) = 2(6p + 7) + 3
6 + (-3 * -9 + 4p * -9) = 2(6p + 7) + 3
6 + (27 + -36p) = 2(6p + 7) + 3
Combine like terms: 6 + 27 = 33
33 + -36p = 2(6p + 7) + 3
Reorder the terms:
33 + -36p = 2(7 + 6p) + 3
33 + -36p = (7 * 2 + 6p * 2) + 3
33 + -36p = (14 + 12p) + 3
Reorder the terms:
33 + -36p = 14 + 3 + 12p
Combine like terms: 14 + 3 = 17
33 + -36p = 17 + 12p
Solving
33 + -36p = 17 + 12p
Solving for variable 'p'.
Move all terms containing p to the left, all other terms to the right.
Add '-12p' to each side of the equation.
33 + -36p + -12p = 17 + 12p + -12p
Combine like terms: -36p + -12p = -48p
33 + -48p = 17 + 12p + -12p
Combine like terms: 12p + -12p = 0
33 + -48p = 17 + 0
33 + -48p = 17
Add '-33' to each side of the equation.
33 + -33 + -48p = 17 + -33
Combine like terms: 33 + -33 = 0
0 + -48p = 17 + -33
-48p = 17 + -33
Combine like terms: 17 + -33 = -16
-48p = -16
Divide each side by '-48'.
p = 0.3333333333
Simplifying
p = 0.3333333333

Find the hypothesis for side a 16 side b 20
I think you mean to say "hypotenuse". If so, then use the pythagorean theorem to get the following
a^2 + b^2 = c^2
16^2 + 20^2 = c^2
256 + 400 = c^2
656 = c^2
c^2 = 656
c = sqrt(656)
c = sqrt(16*41)
c = sqrt(16)*sqrt(41)
c = 4*sqrt(41)
The hypotenuse is exactly 4*sqrt(41) units long
This is approximately 25.612 when you use your calculator.
What is the y-intercept of this graph?
A. 0
B. 2
C. 4
D. 8
Answer: 0
Step-by-step explanation:
The line runs through the coordinate (0,0), rather than starting at (0,2), (0,4), or (0,8).
Always remember that you read coordinates as (x,y) which..
X is how many spaces right or left
Y is how many spaces up or down.
Answer:
A. 0
Step-by-step explanation:
If you can look at the graph it crosses the y-axis exactly at the origin which is 0. This makes 0 the y-intercept because the line intercepts the y-axis at the point (0,0) making our solution A: 0

A charm bracelet costs $65, plus $25 for each charm, write an equation in standard form that represents the total cost y of a bracelet that has x charms please help!
Answer: , y = 65+25x
Step-by-step explanation:
Let x = Number of charms
Given : Fixed cost of bracelet = $65
On addition , cost per charm = $25
Total cost of bracelet = Fixed charge + (Charge per charm) x (number of charm)
If y= total cost.
Then, y = 65+25x , which is the required equation.

Answer:
2 1/3 ssssssssssssddddss
Answer:
You would need 3 to make 1 whole cup
Step-by-step explanation:
Because If we look at it fraction wise
It would be 1/3 right ? and all we need is to make a whole so if we get 3 of 1/3 cups it would be 3/3 . Which equals to 1 cup

I NEED HELP!!!!
(3.2 x 10^4)(1.4 x 10^2)
Evaluate each expression Express result in scientific notation
I need help learning to do this IM GIVING EXTRA POINTS!!!
Step-by-step explanation:
So Scientific Notation is like this.
Ya got a big number that has of 0s . Let's just throw out 69,000,000,000,000
You take the other numbers that arent 0s. Take the first number and put a "." in between it and the second number. So, in this case, you have 6.9, like this.
You then count the number of 0s and +1. So in this case, you'll have 12+1. Which is 13.
You then take the 6.9 and note it with a *10. You then take the 13 and put it on the 10 as an exponent. So in the end youll have 6.9*10^13.
Hopefully, this helps.

Solve the equation 3x-4=8-x
Answer:
x=3
Step-by-step explanation:
3x-4=8-x(Group like terms)
3x+x=8+4(Add both sides)
4x=12(After adding you will proceed to divide both sides by 4)
x=3(x is 3 because 4 can divide 12 3 times that's why we have x as equal to 3)

Will give brainliest if correct.
Answer:
The x-intercept is 4,0. The y-intercept is 0,2.
Step-by-step explanation:
when your finding an intercept you make the other intercept 0. This means the equation to find the x-intercept would look like 5x = 20. This is because they = 0, which means 10 x 0 is 0. Then you use the inverse operation so since it's 5 * x, it will be 20 ÷ 5 which is 4. Do the same thing with the y-intercept. Instead of changing the y to a 0, change the x. Using the inverse operation you get 2.
