Answer:
9
Step-by-step explanation:
Hey There!
If you didnt know the given angles in the triangle added together equal the missing triangles supplement aka z+50
So all we have to do is set up an equation
z+50=30+6x-45
step 1 combine like terms
30-45=-15
now we have
z+30=6x-15
step 2 add 15 to each side
-15+15 cancels out
30=15=45
now we have
z+45=6z
step 3 subtract z from each side
z-z cancels out
6z-z=5z
now we have
45=5z
step 4 divide each side by 5
5/5 cancels out
45/5=9
z=5
so we can conclude that z=9
hope this helps :)
Answer:
hypotenuse = 13.0 cm
Step-by-step explanation:
Given the dimensions of a right triangle whose legs have measures of 13 cm and 1 cm, we can use the Pythagorean Theorem to find the measure of the triangle's hypotenuse.
The <u>Pythagorean Theorem</u> states that the squared measure of a right triangle's hypotenuse is equal to the sum of the squared lengths of its legs. In other words:
Pythagorean Theorem: c² = a² + b²
Let c = hypotenuse
a = Leg₁ = 1 cm
b = Leg₂ = 13 cm
Substitute these values into the given formula to find the measure of the hypotenuse, c:
c² = a² + b²
c² = ( 1 )² + (13)²
c² = 1 + 169
c² = 170
Next, take the square root of c² and 170 to isolate c:

c = 13.04 or 13.0 cm
Therefore, the length of the hypotenuse is 13.0 cm.
Answer:
2 1/6
Step-by-step explanation:
8 2/3 - 7 1/2 = 2 1/6
We want to cut pieces of length:

from 35 metal rods each 40in long, and we want to know how many we can cut.
In order to answer the question, we must compute the number of pieces that we can cut from each metal rod, and then multiply the result by the number of metal rods. Let's do that!
1) From each metal rod we can cut:

2) We have 35 metal rods, so the total number of pieces of 6 1/4 in that we can cut is:

Answer
We can cut 210 pieces from the 35 metal rods.
Remark: we see that by cutting the pieces we will have a waste of metal from each rod.
