Answer:
y = 50, x = 74
Step-by-step explanation:
the total degrees must equal 180. In the left triangle, we are given 80 as in of them. 180-80=100 degrees left in the triangle there are two equal angles left, so we divide 100/2 and get 50, so y=50. In the triangle on the right, there are two equal angles of 53 degrees. So 53x2=106. 180-106= 74 degrees left. x is the only angle left, so x=72
Answer:
no solution
Step-by-step explanation:
Answer:
y=5 or y=−5 it does not matter either one
Step-by-step explanation:
25=y2
Step 1: Subtract y^2 from both sides.
25−y2=y2−y2
−y2+25=0
Step 2: Subtract 25 from both sides.
−y2+25−25=0−25
−y2=−25
Step 3: Divide both sides by -1.
−y2
−1
=
−25
−1
y2=25
Step 4: Take square root.
y=±√25
y=5 or y=−5
Answer:
10.63cm
Step-by-step explanation:
The formula for calculating the distance between two coordinate is expressed as;
D = √(x2-x1)²+(y2-y1)²
Given the coordinates (3, -1) and (-5, 6)
D = √(-5-3)²+(6-(-1))²
D = √(-5-3)²+(6+1)²
D = √(-8)²+(7)²
D = √64+49
D = √113
D = 10.63cm
Hence the shortest distance between P and Q is 10.63cm
