Using the triangle, we can find the angle lengths and using those and trig ratios, find the side lengths. Lets say the top side length is "y".
Using the Law of triangles, we can find the missing angle from 180-90-70=20 deg.
Then we can use the Law of sines,
sin(70)/13=sin(20)/y
y=sin(20)*13/sin(70)
y=15.34
Finally, we use the Pythagorean Theorem, (13)^2+(15.34)^2=x^2
x = 20.1

How far apart are the points (0,-1) and (6,5)?
Answers
Answer:
(6, 6)
Step-by-step explanation:
Answer:
The distance is 8.4853
Step-by-step explanation:
Input Data :
Point 1 (xA, yA) = (0, -1)
Point 2 (xB, yB) = (6, 5)
Objective :
Find the distance between two given points on a line?
Formula :
Distance between two points = √(xB − xA) ^ 2 + (yB − yA) ^ 2
Solution :
Distance between two points = √ (6 − 0)^2 + (5− −1) ^ 2
= √6^2 + 6^2
= √36 + 36
= √72
= 8.4853
Distance between points (0, -1) and (6, 5) is 8.4853
hope this helps and is right :)

Answer:
B reflected over y, translated up
Step-by-step explanation:
The left-right reversal means there was a reflection over a vertical line. The only one among the offered choices is the y-axis.
If the lines are reflected over the y-axis, the points on the y-axis don't move. The intercepts would still be 2 and 5 after the reflection.
However, the y-intercepts have moved up 3 units to 5 and 8.
Lines g and h were reflected over the y-axis and translated up 3 units.

The measures of the angles of a triangle are shown in the figure below. Solve for x.
Answers
Answer:
x = 57
Step-by-step explanation:
Angles of a triangle all add up to 180 so:
x + 78 + 45 = 180
x + 123 = 180
x = 180 - 123
x = 57
