________________________________
<u>Given:</u>
(2+√3)+(4-√3)
<u>To Find:</u>
Evaluate the expression
<u>Solution:</u>
<u>⇨</u><u>Step 1:</u>
Remove the parentheses
(2+√3)+(4-√3)
When there is + or no sign in front of an expression in parentheses, the expression remains the same
= 2 + √3+ 4-√3
<u>⇨</u><u>Step 2:</u>
Cancel the opposite terms √3 and -√3
"Two numbers are opposites if they have the same absolute value but different signs"
= 2 + 4
<u>⇨</u><u>Step 3:</u>
Add the numbers
= 6
<u>Hence (2+√3)+(4-√3) = 6</u><u>.</u>
Answer:
C
Step-by-step explanation:
Use the slope formula:
m = (y2 - y1) / (x2 - x1)
m = (-3 - 2) / (5 - 3)
m = -5/2
Which one to do cuz it’s confused
Answer:
75 degrees.
Step-by-step explanation:
All interior angles of a triangle add up to 180.
So we can set up an equation: 65+40+x=180
105+x=180
x=180-105
x=75
Answer:
Step-by-step explanation:
KL = JK, so ΔJKL is an isocesles triangle, then m∠J = m∠L
KL is a tangent line, so ∠JKL = 90°,
so m∠J = 45°
