Answer:
This is khan academy. I am pretty sure they have a video for this but whatever.
Step-by-step explanation:
So we are using sin, cosine, and tan. 3.4 is the hypotenuse. the side is X. The angle is 20 degrees. So, this is adjacent to hypotenuse. This means it is cosine.
3.4cos(20)= around 3.19
And thats that! let me know if this is wrong and I will try to fix it.
Step-by-step explanation:
6-8/1- -1 = -2/2 = -1 is the slope
y - 8 = -1(x+1)
Sorry but i only know the answer for the 1st question.
--------------------------
If the angles are complementary they measure 90°.
1st find half of 90
which is 45.
Find 4 more than 45.
which is 49°
then subtract 90-49=41
so the measurement of the 2 angles are
49 and 41
Hope it helps!!
Answer:
y = 28
Step-by-step explanation:
since this is an Isosceles triangle (x - 5)° must be equal to 34°
x - 5 = 34
x = 39
the sum of interior angles in a triangle is equal to 180°
if the two angles 34 + 34 = 68
Then the third angle is 180 - 68 = 112°
4y = 112
y = 28
We need to compute the diagonal of yhe square.
d²=7²+7²=49×2cm²
d=7×sqrt(2)=7×1.41=9.87cm.
The diagonal we just computed is the diameter of the circle that contains the square.
Since d=9.87 < 11, then indeed, the square fits inside the circle, without touching it.
