Answer:
B. 120°
Step-by-step explanation:
If two tangents intersect in the exterior of a circle, then the measure of the angle formed is one half the difference of the measures of the intercepted arcs.
m∠A° = 1/2(300 - 60)
m∠A° = 1/2(240)
m∠A° = 120
Answer:
The 2 numbers are 512.8 and 487.2.
Step-by-step explanation:
Let the numbers be x and y, then:
x + y = 1000............(1)
x^2 - y^2 = 25600
(x + y)(x - y) = 25600
1000(x - y) = 25600
x - y = 25.6............(2)
Adding (1) + (2):
2x = 1025.6
x = 512.8
so y = 1000 - 512.8
y = 487.2.
Plug in 50
-6(50) + 150
-300 + 150 = -150
The solution is -150
(x-3)² ⇒ (x-3)(x-3)
(x-3)(x-3) = x(x-3) -3(x-3) ⇒ x² - 3x - 3x + 9 ⇒ x² - 6x + 9
The 3rd option is the correct answer. x² - 6x + 9
Answer:
9
Step-by-step explanation:
- 36 = 5x
- 36 = 5x
-5x = 36
- 45 = 36
+ 45 + 45
-----------------------
81 = 81 ✅
- 36 = 5(9)
81 - 36 = 45 ✅
