Find <ABC =2x and <CBD=3x-10​
Romashka-Z-Leto [24]

Answer:

x = 20

Step-by-step explanation:

m<ABC and m<CBA are complementary angles which means their sum is 90 degrees:

2x + 3x - 10 = 90 add like terms

5x - 10 = 90 add 10 to both sides

5x = 100 divide both sides by 5

x = 20 to find the angles replace x with 20

m<ABC = 40 and

m<CBA = 50

What is the exact distance from (-5, 1) to (3,0)? (4 points)
frez [133]

Answer:

The exact distance is √65 units

Step-by-step explanation:

To solve this problem we first have to make the difference between (-5, 1) and (3, 0)

(3 , 0) - (-5 , 1) =

3 - (-5) = 8

0 - 1 = -1

(8 , -1)

Now that we have the distance in x and r we can use Pythagoras to calculate the distance of the diagonal

a = 8

b = -1

h² = a² + b²

h² = 8² + (-1)²

h² = 64 + 1

h² = 65

h = √65

The exact distance is √65 units
