T = 4
divide each term by 2 and simplify
2(t+1)/2 = 10/2
t+1 = 10/2
t+1=5
t=5-1
t=4
Well the slope would be m=-5/4 and the y-intercept would be 1 because of y=mx+b
10x+2x+13=145
angle of WIJ and HIW is equal to 145 degrees
12x+13=145
12x=132
x=11
angle of WIJ is 10x
angle of HIW is 2x+13
to find angle of HIW, you plug in x=11 into 2x+13 and
the answer and angle of HIW is 35 degrees.

<h3>Base and height of a triangle </h3>
From the question, we are to match the base to the corresponding height
In a triangle, the height of the triangle is perpendicular to the base.
Applying this in the given diagram,
The first base matches the second height
The second base matches the first height
The third base matches the third height

Answer:
<u>The number of pens = 120 and the number of pencils = 200</u>
Step-by-step explanation:
Let the number of pens x, and the number of pencils is y
the cost of one pen $1, and the cost of one pencil $0.5
The cost of the whole purchase was $220
1 * x + 0.5 * y = 220
x + 0.5 y = 220 ⇒ eq.(1)
there were 80 more pencils than pens
y - x = 80 ⇒ eq.(2)
from eq.(2) x = y - 80
By substitution with x from the last equation at eq.(1)
∴ (y - 80) + 0.5 y = 220
1.5y = 220 + 80 = 300
y = 300/1.5 = 200
x = y - 80 = 200 - 80 = 120
<u>So, the number of pens = 120 and the number of pencils = 200</u>
