Find the length of the indicated side in each triangle, to nearest unit.

gogolik [260]

Answer:

A= 56

E= 59

Step-by-step explanation:

All triangle are 180 degrees so

71 + 53 = 124

180- 124 = 56

70 + 51 = 121

180 - 121 = 59

Hope this helps

MAX is equiangular. If m<M = (7x + 4)⁰ m<A = (12x - 36)º, and m<X = (10x – 20)⁰, find x.

Musya8 [376]

Answer:

x = 8

Step-by-step explanation:

Since the triangle is equiangular then the 3 angles are congruent and of measure 60°.

Equate any of the 3 angles to 60 and solve for x, that is

7x + 4 = 60 ( subtract 4 from both sides )

7x = 56 ( divide both sides by 7 )

x = 8

A fruit company delivers its fruit in two types of boxes: large and small. A delivery of 5 large boxes and 3 small boxes has a t

faltersainse [42]

Answer:

one large box equals 15.75kg

one small box equals 13.75kg

Step-by-step explanation:

First, identify your variables:

Let "l" represent the weight of one large box.

Let"s" represent the weight of one small box.

Then, stack the two equations on top of each other:

$5l+3s=120\\7l+9s=234$

Next, multiply the first equation by 3 so we can use elimination of the "s" variable to find the "l" variable first:

$3(5l+3s=120)\\7l+9s=234\\\\15l+9s=360\\7l+9s=234$

Now, subtract the two equations to cancel out the s-variable and find the l-variable:

$15l+9s=360\\-(7l+9s=234)\\8l=126\\\frac{8l}{8}=\frac{126}{8}\\l=15.75$

Then, substitute your l-variable in the original first equation to find the s-variable:

$5l+3s=120\\5(15.75)+3s=120\\78.75+3s=120\\78.85-78.75+3s=120-78.75\\3s=41.25\\\frac{3s}{3}=\frac{41.25}{3}\\s=13.75$

With all the information that is collected, you find that one large box weighs 15.75kg and one small box weighs 13.75kg.
