The two short sides of a triangle are 3 and 4 inches. what is the length of the hypotenuse,in inches?​
disa [49]

Answer:

The length of the hypotenuse is 5 inches.

Step-by-step explanation:

The formula for finding the hypotenuse is a^{2} + b^{2} = c^{2},

with a and be being the two shorter sides of the triangle, while c is the hypotenuse.

Let's plug in our values for a and b and solve.

4^{2} + 3^{2} = c^{2}

16 + 9 = c^{2}

25 = c^{2}

What is the square root of 25? 5.

The length of the hypotenuse is 5 inches.

If DGH ~ DEF, Find the value of X
DIA [1.3K]

Answer:

x=25

Step-by-step explanation:

we know that

DGH ~ DEF ---> given problem

Remember that

If two triangles are similar, then the rtio of its corresponding sides is proportional and its corresponding angles are congruent

so

\frac{DG}{DE}=\frac{GH}{EF}

substitute the given values

\frac{52}{91}=\frac{x+3}{2x-1}

(2x-1)52=(x+3)91\\104x-52=91x+273\\104x-91x=273+52\\13x=325\\x=25
