Answer:
Step-by-step explanation:
Since π=3.14 and 1.75 should be half of π so cos(1.75) should be in the approximation of
or
.
Clearly Sam's calculator is in the degree mode since 
is about
and obviously,
, So on the unit circle, it will be in the second quadrant.
Thus, cos(1.75) is negative.
Hello!
To find the area of a trapezoid you use the equation

A is area
h is height
a and b are the bases
Put in the values we know

Add

Divide

Multiply
A = 120
The answer is 120cm squared
Hope this helps!
Like terms" are terms whose variables (and their exponents such as the 2 in x2) are the same. In other words, terms that are "like" each other. Note: the coefficients (the numbers you multiply by, such as "5" in 5x) can be different.
♥It says that he adds 12$ each week, and by the end of 3 weeks he had 60. Well if you do 12*3
And that =36.
But as you can see its not 60 so we have to find out how much money he had in there before.
He had 24$ in there before he started doing this.
You can find this by doing 36+x=60 and 36+24=60.
Now if you do 12*15
You get 180.
Now add the 24 dollars he already had in there.
180+24=204
He had 204$ at the end of wk.15
