Triangle ABC is an equilateral triangle with side AB, BC, and AC. If side BC is equal to 10 cm what is the measure of side AC?

nordsb [41]

Answer:

AC = 10 cm

Step-by-step explanation:

We are givne with a triangle ABC is an equilateral triangle with side AB, BC, and AC. We are given that side BC is equal to 10 cm . We are required to find the measurement of side AC.

The basic property of any equilateral triangle is that all the sides are equal. Hence

AB = BC = CA

BC=10 cm

Hence, AB = 10 cm and also AC=10 cm

Combine like terms to create an equivalent expression.

Lelu [443]

Answer:

$\frac{1}{6}$ p - $\frac{4}{5}$

Step-by-step explanation:

collect like terms

- $\frac{2}{3}$ p + $\frac{5}{6}$ p + $\frac{1}{5}$ - 1

= - $\frac{2(2)}{2(3)}$ p + $\frac{5}{6}$ p + $\frac{1}{5}$ - $\frac{5}{5}$

= - $\frac{4}{6}$ p + $\frac{5}{6}$ p - $\frac{4}{5}$

= $\frac{1}{6}$ p - $\frac{4}{5}$

A packaging company is planning is in the planning stages of creating a box that include a three dimensional support inside the

Oliga [24]

Answer:

The length of the diagonal support is 69 feet.

Step-by-step explanation:

Dimensions of the box: length = 6 feet

width = 5 feet

height = 8 feet

The diagonal support relates with the diagonal of the base and the height.

From the base of the box, let the length of its diagonal be represented by x. Applying Pythagoras theorem;

$/Hyp/^{2}$ = $/Adj 1/^{2}$ + $/Adj 2/^{2}$

$x^{2}$ = $6^{2}$ + $5^{2}$

$x^{2}$ = 36 + 25

= 61

x = $\sqrt{61}$

= 7.81

let the length of the diagonal support be represented by l. So that;

$/Hyp/^{2}$ = $/Adj 1/^{2}$ + $/Adj 2/^{2}$

$l^{2}$ = $x^{2}$ + $8^{2}$

= $\sqrt{61}$ + 64

l = $\sqrt{\sqrt{61} + 64 }$

= 61 + 8

= 69

Thus, the length of the diagonal support is 69 feet.
