Answer:

x = 12

Step-by-step explanation:

This is the type of problem where you are always asked to find out the length of a side

Use Pythagorean Theorem.

Pythagorean Theorem: a^2 + b^2 = c^2 where a = 5 b = x and c = 13

And it makes sense because c is the largest side out of all of em

Anyways substitute a b and c for their given values!

5^2 + x^2 = 13^2

Solve for the exponents

25 + x^2 = 169

x^2 = 169 - 25

x^2 = 144

but that’s not the answer because it is way too large to fit in the shape so square root 144

Square root of 144 = 12

Therefore, x = 12

If triangle FGH, FG=8.7, FH=4.5 and GH=6.1, Which is the smallest angle of the triangle
jolli1 [7]

∠G is the shortest

Step-by-step explanation:

Given is a ΔFGH

FG = 8.7

FH = 4.5

GH = 6.1

The triangle will be formed with three angles

F, G and H

"The side opposite to the largest angle of the triangle is the largest"

Similarly, The side opposite to the shortest angle is the shortest.

Converse of this postulate will be:

The interior angle opposite to the shortest side of the triangle is the smallest.

The triangle formed is attached in the form of a picture.

The angle opposite to FH will be the shortest.

Hence,

∠G is the shortest

Which equation matches the graph below?
Oksana_A [137]

Answer:Given that the graph shows tha the functión at x = 0 is below the y-axis, the constant term of the function has to be negative. This leaves us two possibilities:

y = 8x^2 + 2x - 5 and y = 2x^2 + 8x - 5

To try to discard one of them, let us use the vertex, which is at x = -2.

With y = 8x^2 + 2x - 5, you get y = 8(-2)^2 + 2(-2) - 5 = 32 - 4 - 5 = 23 , which is not the y-coordinate of the vertex of the curve of the graph.

Test the other equation, y = 2x^2 + 8x - 5 = 2(-2)^2 + 8(-2) - 5 = 8 - 16 - 5 = -13, which is exactly the y-coordinate of the function graphed.

Completethe equationso that it has no solution.5x – 4 = 5 + ?​
Naddik [55]

Step-by-step explanation:

5x−4=5

1 Add 44 to both sides.

5x=5+4

5x=5+4

2 Simplify 5+45+4 to 99.

5x=9

5x=9

3 Divide both sides by 55.

x=\frac{9}{5}

x=
