Answer:
a=25
Step-by-step explanation:
since angle T is 60, and angle Y is the exact same as T, it would make sense that a=25 [3(25)-15]
12x - 4y = 20 Subtract 12x from both sides
-4y = -12x + 20 Divide both sides by -4
y = 3x - 5
9.42 Units
Step-by-step explanation:
Since the angle shown is 90 degrees we can deduce that the rest of the arc is 270 degrees therefore we can make the fraction:
270/360; 360 being the total angle measurement of a circle
270/360 simplifies to 3/4
The fraction represents how much of the circle that arc covers
Now we have to find the circumference which would be
2(3.14)r
r = 2 therefore: 2(3.14)2 = 12.56
Now that we have the circumference of the WHOLE circle we multiply it by 3/4 to find out the arc length
Which gives us 9.42
Answer:
5 kg because
Step-by-step explanation:
45000 g = 45 kilo
50 - 45 = 5 Kg
Answer:
x = 12
A = 30
Step-by-step explanation:
Here, we want to solve for the value of x
The angle at the top of the triangle is 8x + 4
The reason for this is because vertically opposite angles are equal
Mathematically;
8x + 4 + 3x - 6 = 130
The reason for this is that opposite interior angles equal the exterior angle
Thus;
8x + 3x + 4- 6 = 130
11x -2 = 130
11x = 130 + 2
11x = 132
x = 132/11
x = 12
The value of A is 3x - 6
A = 3(12)-6
A = 36-6
A = 30
