Answer:
b = 12
Step-by-step explanation:
Complementary angles add to 90 degrees
a+b = 90
78+b = 90
Subtract 78 from each side
78-78+b = 90-78
b = 12
500,000 is the answer as 2 isn’t higher then 5.
Answer:
2 ways
Step-by-step explanation:
4 to 2 and 3 to 3
Answer:
you solve these by plugging the numbers into pythagorean theorem which is
a^2 + b^2 = c^2 (a squared plus b squared equal c squared)
C is the hypotenuse which is the longest side across from the right angel (assuming all these problems are for right triangles)
so 17 would be 9.5^2 + 3.8^2 = c^2
So 90.25 + 14.44 = c^2
104.69=c^2
Then to solve for c take the square root of each side and get
10.23=c
To do the other ones where a or b doesn’t have a value, it’s almost the same but you just have to plug in the variables in different places and solve it
Step-by-step explanation:
To answer, find the distance from point C to D, point D to E, point E to F, and point F to C. The formula for the distance is,
d = sqrt ((x2 - x1)² + (y2 - y1)²)
Point C to D d1 = sqrt ((-3 - -2)² + (1 - 4)²) = 3.16 units
Point D to E d2 = sqrt ((1 - -3)² + (0 - 1)²) = 4.12 units
Point E to F d3 = sqrt ((-1 - 1)² + (2 - 0)²) = 2.83 units
Point F to C d4 = sqrt ((-1 - -2)² + (2 - 4)²) = 2.23 units
Then, add up all the distances and the answer is 12.34 units. The closest answer is letter D. Credit:Meerkat
