Answer:
x = 128 degrees
Step-by-step explanation:
all triangles contain 180 degrees
the upper left corner angle is 52 degrees because 180 -90 - 38 = 52.
angle x is supplementary to 52 degrees so x = 180 -52 = 128 degrees
Question
1/5x - 2/3y = 30 , when y = 15
Answer:
<h2>
200</h2>
Step-by-step explanation:
replace y with 15
1/5x - 2/3 * 15 = 30
1/5x - 10 = 30
1/5x = 40
x = 40 * 5
x = 200
Answer:
x = 4
Step-by-step explanation:
Given that the triangle is equilateral then the measure of each angle is 60°
Equate 9x + 24 to 60 and solve for x
9x + 24 = 60 ( subtract 24 from each side )
9x = 36 ( divide both sides by 9 )
x = 4
Answer:
Step-by-step explanation:
First let's find the value of 'p-q':
To find |p-q| (module of 'p-q'), we can use the formula:
Where 'a' is the coefficient of 'i' and 'b' is the coefficient of 'j'
So we have:
Now, we need to find the module of p and the module of q:
Then, evaluating |p-q|-{|p|-|q|}, we have:
