Answer:
38
Step-by-step explanation:
Notice that the first triangle is an isosceles triangle, meaning that the base angles are equivalent. Since one angle is 62, we know that the other is 62 as well, which makes 124. This means that angle 2 is 56 degrees. Since 2 and 3 are on the same 'line', they both add up to 180. If 2 is 56, then angle 3 is 124. So the three angles inside the triangle are 124, 18, and x. So, 124+18=142. 180-142= 38
∠1 and ∠2 are RIGHT ANGLES, VERTICAL ANGLES, and SUPPLEMENTARY ANGLES.

Answer:
Step-by-step explanation:
First we define two generic vectors in our 
space:
By definition we know that Euclidean norm on an 2-dimensional Euclidean space is:
Also we know that the inner product in space is defined as:
So as first condition we have that both two vectors have Euclidian Norm 1, that is:
and
As second condition we have that:
Which is the same:
Replacing the second condition on the first condition we have:
Since 
we have two posible solutions, 
or 
. If we choose , we can choose next the other solution for 
.
Remembering,
The two vectors we are looking for are:
11.) You pay 620 to rent a hotel room for 4 weeks. Total cost include an initial deposit plus a weekly fee of 125.
a)y=(rate per week)x+deposit
620=125x+deposit
620=125(4)+deposit
620=500+deposit
620-500=deposit
120=deposit
y=125x+120
b) y-intercept is the deposit, at 120
