What is the value of x if a triangle has two 50 degree angles?
If you meant x to be the third interior angle, x would equal 80, because the sum of all three interior angles of a triangle equals 180. So 80+50+50=180
What is 12 x 15?
27
Find the supplementary angle of 148.7?
Supplementary angles add up to 180 degrees. So, if x is the supplementary angle to 148.7 degrees, solve for x: 148.7+x=180 x=180-148.7=31.3 degrees
Explain Why an angle that is supplementary to an acute angle must be an obtuse angle?
If x is acute, then x < 90 and -x > -90. Adding 180 to both sides, 180-x > 90, i.e. the supplement of x is obtuse.
What is 2x plus 15 plus 2x equals 180?
First of all add all common factors. In par. (2x) + 15 + (2x) = 180 4x + 15 = 180 Divide 4x and 180 by 4. (4x/4) + 15 = (180/4) x + 15 = 45 Then subtract 15 to 15 and 45. x + (15-15) = (45-15) x = 30 Answer is X = 30.
X plus x plus x equals 180 then what is the value of x?
60
How do you find supplementary angles to find value of X?
180-x...... hahaahahaaa
What is the sine of 180?
The sine of 180 degrees is 0. Remember, the sine value on a unit circle is the y-value. If you find f(pi) in the function f(x)=sin(x), you will get zero as an answer.
What two numbers when multiplied together will give you -180 and when added together will give you 1?
-179
Verify cot x-180 cot x?
cot x = (cos x) / (sin x) cos (x - 180) = cos x cos 180 + sin x sin 180 = - cos x sin (x - 180) = sin x cos 180 - cos x sin 180 = - sin x cot (x - 180) = (cos (x - 180)) / (sin (x - 180)) = (- cos x) / (- sin x) = (cos x) / (sin x) = cot x
How do you write 180 in expanded notation?
Expanded notation is writing the number to show the value of each digit. 180 = (1 x 100) + (8 x 10) + (0 x 1)
What number can you use to equal 180 without passing eighty-nine?
3 x 60 = 180 4 x 45 = 180 5 x 36 = 180 6 x 30 = 180 9 x 20 = 180 10 x 18 = 180 12 x 15 = 180
What are the factor pairs of 180?
The factor pairs of 180 are 1 x 180, 2 x 90, 3 x 60, 4 x 45, 5 x 36, 6 x 30, 9 x 20, 10 x 18, and 12 x 15.
What is 60 of 180?
60 of 180 = 60 x 180 = 10,80060% of 180 = 180 x 0.6 = 10860% off 180 = 180 x 0.4 = 7260 off 180 = 180 - 60 = 120
How do i find the value x in a scalene angle?
If it is a scalene triangle then: 180 - the sum of the 2 known angles = x angle
55 plus what equals 180?
55 + x = 180 x = 180 - 55 x = 125
7x-3 plus 5x plus 15 180?
If you mean: 7x-3+5x+15 = 180 then the value of x works out as 14
