Since 480 is les than 2kπ (or 2k.180°), then k = 1
480-360 = 120°
Answer:
y = (3/2)x - 5/2
Step-by-step explanation: 5 + 2x
-2x-3y=5, solved for y, is y = ------------- , with a slope of -2/3. A line
-3
perpendicular to this one has a slope which is the negative reciprocal of -2/3, that is, +3/2. Using the slope-intercept formula, we calculate the y-intercept of the line that is perpendicular to the given one and passes through (1/3, -2): y = mx + b => -2 = (3/2)(1/3) + b, or
-2 = 1/2 + b. Thus, b must be -2 1/2, or -5/2.
The desired equation is y = (3/2)x - 5/2.
Answer:
Option (1)
Step-by-step explanation:
From the triangles given in the picture,
Since, JK ≅ KL [Given]
JM ≅ ML [Given]
KM ≅ KM [Reflexive property of congruence]
ΔJMK ≅ ΔLMK [SSS property of congruence]
Therefore, ∠JKM ≅ ∠LKM [CPCTC]
(2x + 5) = (3x - 6)
3x - 2x = 5 + 6
x = 11
m∠JKL = m∠JKM + m∠LKM
= (2x + 5) + (3x - 6)
= 5x - 1
= 5(11) - 1
= 54
Option (1) will be the answer.
