Answer: 21.8
Step-by-step explanation:
Pythagorean Theorem = a^2 + b^2 = c^2
5^2 + b^2 = 10^2
25 + b^2 = 100
b^2 = 75
b = 8.7
area = 1/2bh
1/2 5x8.7
1/2 43.5
21.8
Answer:
x = 21
Step-by-step explanation:
Diagonal angles are equal to eachother, so 143 = 6x +17
143 = 6x + 17
Subtract 17 from both sides
126 = 6x
Divide by 6
21 = x
To check put x as 21
143 = 6(21) + 17
Mutiply 6 by 21
143 = 126 + 17
add 17
143 = 143
Answer:
- 4
Step-by-step explanation:
The conjugate of - 2 + i is - 2 - i, thus
- 2 + i + (- 2) - i
= - 2 + i - 2 - i ← collect like terms
= - 4 ← in the form a + bi with b = 0
