A. 2x3=6 and 6x12=72 so 78 is greater than 36
6+72=79 which is less than 90
Answer:
These are all equivalent to the ratio of 1:2
Step-by-step explanation:
Answer:
2, 8, 90, 160
that is the focal, vertex l, direction
Answer:
y is equal to 2 and x is equal to 31 degrees.
Step-by-step explanation:
In order to find this, we must note that similar parts of congruent triangles are congruent. Since y is congruent to the part that is labeled 2, then it is an easy comparison.
x is a bit trickier. For this one, we must find the missing angle of the first triangle. To get that, we must subtract the given angle and the right angle from 180. This will give us x.
180 - 59 - 90 = x
31 = x
Answer:
Step-by-step explanation:
The figure is composed of 3 Right triangles. To find the values of the variables x and y we use the Pythagorean theorem to propose one equation.
Now we solve for x
Let's call z at the angle opposite to y
Then we have that:
Where
Now we use this angle to find the length y
Where in this case
