notsponge [240]
Since the three angles of a triangle add to give 180°

The the size of the largest angle 4 = 180° × \frac{4}{2+3+4}
                                                       =  180° × \frac{4}{9}

∴ the size of the largest angle = 80°

An instrument maker creates a triangle in the shape of an isosceles triangle by bending a metal rod. the rod is 13 inches long,
Gre4nikov [31]

The length of the longest slide is 5 inches. he other two sides will be 4  inches in length.

<h3>Length of the longest slide</h3>

Isosceles triangle

Given:

Total length=13 inches

Hence:

AC=BC<AB

Let AC=BC=x-1 inches

AB=x inches

Thus:

x-1+(x-1)+x=13

3x-2=13

3x=13+2

3x=15

divide both side by 3x

x=15/3

x=5 inches

Hence:

Other two side

x-1=5-1=4 inches

Therefore the length of the longest slide is 5 inches. he other two sides will be 4  inches in length.

The sum of two numbers is 2. Their difference is -16. What is the first number?
Helen [10]

Answer: The first number is 4

Explanation: Since the sum of the two numbers is ten, x + y = 10

Also, since the difference of the two numbers is two, then x - y = 2

Since x - y = 2, another way to write that is x = y + 2 and since x is exactly the same as y + 2, we can plug in "y + 2" in place of x in the first equation (x + y = 10) to get (y + 2) + y = 10. Then we solve this equation by combining like-terms.

2y + 2 = 10

2y = 8

y = 4

Since x = y + 2, x = 4 + 2 or x = 6

I hope this helped you!

James practiced Piano for 48 Minutes. Alisa practiced 5 times long as James. How many Minutes did Alisa Practice? how many minut
ANEK [815]

Answer:

Alisa practiced for 240 minutes (4 hours). In total, they practiced for 288 minutes (4.8 hours).

Step-by-step explanation:

If James practiced for 48, and Alisa practiced 5 times as long, then we would multiply 48 by 5 (240 minutes).

If we want to find how many minutes in total they practiced, then we would add 240 minutes (Alisa's practice time) and 48 minutes (James' practice time) together, which would equal 288 minutes (4.8 hours).

Equation: y=48+x
