Answer:
Option (1)
Step-by-step explanation:
By using triangle sum theorem in the given triangle,
(5x - 7)° + (11x - 4)° + (3x + 1)° = 180°
(5x + 11x + 3x) - (7 + 4 - 1) = 180
19x - 10 = 180
19x = 190
x = 10
Therefore, (3x + 1)° = 30 + 1
= 30°
(11x - 4)° = 110 - 4
= 106°
(5x - 7)° = 43°
Therefore, Option (1) will be the correct option.
81/4
Step-by-step explanation:


9=4x/9
81=4×
x=81/4
adding logs means elements are multiplied, subtracting means divide. number in front of log is raised to power
base of log is raised to power of element after =
element in log is then equal to log base raised to power
solve resulting equation
Add n on both sides:
3m = km - 8 + n
Subtract km on both sides:
3m - km = n - 8
Factor the Left-Hand Side:
m(3 - k) = n - 8
Divide both sides by (3 - k):
m = (n - 8) / (3 - k)
6(7 + 5) + 3 =
6(12) + 3 =
72 + 3 = 75
Answer:
3.69 mm
Step-by-step explanation:
So it's a right triangle so you can use a^2+b^2=c^2
Plugging in what we know the equation becomes:
2.8^2+2.4^2=c^2 (C = x because x is the hypotenuse)
7.84+5.76=c^2
13.6=c^2
The square root of 3.68782 which rounds to 3.69
So x=3.69mm
