If a triangle is 12 inches high and has a 20 inch long hypotenuse then how wide is it?

Ber [7]

Answer:

The triangle should be 16 inches wide.

Step-by-step explanation:

$\text {Use the Pythagorean Theorem to solve for the leg.}\\a^2 + b^2 =c^2$

What we know:

One of the legs measures 12 inches.

The hypotenuse is 20 inches.

We need to solve for b. Solving for a while b is 12 would also be acceptable.

$12^2 + b^2 = 20^2 \text { OR } a^2 +12^2=20^2$

We will use the first equation.

$12^2 + b^2 = 20^2\\12 * 12 = 144\\20 * 20 = 400\\\\\boxed {144 + b^2 = 400}$

$\text {Subtraction property of equality: }\\144-144+ b^2 = 400-144\\\boxed {b^2 = 256}\\\\\text {Take the square root of 256: }\\\sqrt{256}=\sqrt{b^2} \boxed {16 = b}$

The triangle should be 16 inches wide.

Given the trinomial 3x2 − 6x + 5, what is the value of the discriminant?

yan [13]

$\bf \begin{array}{llcccll}
& 3 x^2& -6 x& +5\\
&\uparrow &\uparrow &\uparrow \\
&a&b&c
\end{array}
\\\\\\
discriminant\implies b^2-4ac\implies (-6)^2-4(3)(5)$

Which ones apply to these triangles? ABC congruent to UVW

Reika [66]

Angle A = angle U since they're both right angles (both 90 degrees). This is what the square marker means.

segment AC = segment UW

Angle C = angle W because they have the same angle marker

---------------------

we have two pairs of congruent angles, with segments between them that are congruent. So we use the ASA property

The final answer is choice E.

nexus9112 [7]

Answer:

It’s going to be 10/15 he answered correctly.

Step-by-step explanation:

It’s 10/15

If you want to know a easy way to find the answer for some cases, questions you can subtract it the whole number of questions, and you just do 15 - 5 = 10

So he got 10 questions right out of 15.
