Answer:
X=20
Y=70
Step-by-step explanation:
All angles within a triangle add up to 180
180 - 40 = 140
140 is the top angle of the big triangle
140 + x + x = 180
x = 20
Now use x to find y by subtracting from the right angle (90 degrees)
90 - 20 = 70
70 + 40 + y = 180
Y = 70
3√10^4x is equivalent to -√10 3/4^x and -4√10^3x they are all equivalent
Answer:
m= 4
Step-by-step explanation:
3m +2n= 16 -----(1)
m -2n= 0 -----(2)
From (2):
m= 2n -----(3) (+2n on both sides)
subst. (3) into (1):
3(2n) +2n= 16
6n +2n= 16
8n= 16 (simplify)
n= 16 ÷8
n= 2
subst. n=2 into (3):
m= 2(2)
m= 4
Hi there! The answer is 15/8.
The general formula for the tangent is
When we fill in the data from the picture, we get the following:
Answer:
84 m² is the correct answer.
Step-by-step explanation:
first, split the parallelogram into three shapes: the two triangles on either side of the shape, and the rectangle in the middle.
the formula for the area of a triangle is base x height / 2. all of the measures are indicated in the picture so that means that 4 x 7 / 2 = 14. since there are two triangles, add 14 + 14 = 28.
then, find the area of the rectangle. the area of a rectangle is length x width. 8 x 7 = 56.
56 + 28 = 84.
