A given angle measures 90°.. Then, note that the total measurement of the triangle is 180°... Subtract 180° by 90°, and the other angles must add up to 90°!
Good luck!
The answer is C or the third option
Answer:
2 real solutions
Step-by-step explanation:
To determine the nature of the solutions use the discriminant
Δ = b² - 4ac
• If b² - 4ac > 0 then 2 real solutions
• If b² - 4ac = 0 the 2 real and equal solutions
• If b² - 4ac < 0 then no real solutions
Given
x² + 9x + 20 = 0 ← in standard form
with a = 1, b = 9, c = 20, then
b² - 4ac
= 9² - (4 × 1 × 20 ) = 81 - 80 = 1
Since b² - 4ac > 0 then there are 2 real solutions
The slope is 2 i’m pretty sure
Answer:
W =1 1/4Step-by-step explanation:
Let W = what
W - 1/2 = 3/4
Add 1/2 to each side
W -1/2 +1/2 = 3/4+1/2
W = 3/4+1/2
Getting a common denominator of 4
W =3/4+1/2*2/2
W =3/4 +2/4
W = 5/4
Changing to a mixed number
W = 4/4 +1/4
W = 1 +1/4
W =1 1/4
