Answer:
x=93°
Step-by-step explanation:
Angles in a triangle equals 180°
Represent the unknown angle in the triangle with y.
35°+58°+y=180°
93°+y=180°
y=180°-93°
y=87°
Angles on a straight line equals 180°
x=180°-87°
x=93°

Answer:
x + 3
Step-by-step explanation:
3x+2 is the 2nd term
2x-1 is the commind difference (d)
so you just need to substract it
3x+2
-(+2x-1) -------transpose -2x+1
3x+2
-2x+1
---------
x+3
Answer:
Q1) D
Q2) C
Step-by-step explanation:
Q1)
y ∝ x
y = kx
Let x=-1,y=2
2 = k(-1)
k = -2
Q2)
directly (y=kx)
Let x=2,y=4
4 = k(2)
k = 2
y = 2x
inverse (y = k/x)
Let x=2,y = 4
4 = k/2
k = 8
xy = 8
The solution is B. (3,-2)
To solve this problem, we have to set up a proportion, letting x represent the unknown height of the tree.
5 feet/8 feet = x feet/ 32 feet
To solve this equation, we have to use cross products, or the multiplication of the numerator of one fraction by the denominator of the other fraction, and setting them equal to one another.
5(32) = (8)x
When simplified, as we multiply the numbers on both sides of the equations, we get the equation:
160=8x
20=x
Therefore, if a tree's shadow is 32 feet long, the height of the tree is a) 20 feet.
