Hello from MrBillDoesMath!
Answer:
45 (all three: 45, 45, 90)
Discussion:
Let "x" be the base angle in the isosceles triangle. As base angles are equal in an isosceles triangle and a triangle contains 180 degrees:
x + x + 90 = 180 =>
2x + 90 = 180 => subtract 90 from both sides
2x = 180 -90 =>
2x = 90 => divide both sides by 2
x = 45
Thank you,
MrB
Answer:
66cm²
Step-by-step explanation:
Okay so lets start by breaking this down and writing a smiple equation to find the area.
We know that the N's are the same size. To make it easier we can turn them to a square/rectangle. I think it would be easist to move the bottem N's to the top. (look at the pic attached to see what i mean)
Lets start by finding the area of the top rectangle. We need to divide 8 by 2 to find the height.
a = b * h
a = 12 * 4 = 48(area of top rectangle)
a(of m) = 4.5 * 4 = 18
area of the whole thing:
a = 48 + 18 = 66
Answer:
3/1
Step-by-step explanation:
Given the expression 6/4/2, we are to express as a single fraction.
6/4/2
= 6÷4/2
= 6×2/4
= 12/4
= 3/1
Hence the expression as a single fraction is 3/1
hi <3
this is a lot simpler if you just ignore the variable (basically the letter)
now you have -10 - 1
which gives you -11
now just add back on the variable to give you your answer of:
-11x
hope this helps :)
Use the identity
sec^2x = 1 + tan^2 x
- so sec x = sqrt(1 + tan^2 x) then:-
tan x + sqrt( 1 + tan^2 x) = 1
sqrt ( 1 + tan^2 x) = 1 - tan x
1 + tan^2 x = 1 + tan^2x - 2 tan x
0 = -2 tanx
tan x = 0
x = 0, π
π is an extraneous root because sec 180 = -1
So the answer is 0 degrees
