Answer:
91
Step-by-step explanation:
given perimeter = 273
perimeter of equilateral triangle = 3a
3a = 273
a = 273/3
a = 91
hence, length of side of the triangle is 91
Answer:
x² + 1 = 0
a = 1
b = 0
c = 1
There is no real solution because the discriminant is negative
Note.
Formula diskriminan
√b² - 4ac.
if the diskrimanan is negatif, so the quadratic equatoin dont have solution
∠A must be 2*22=44 because it is made up of two times y.
A triangle's corners should add up to 180, so B and C together are 180-44=136. Divide 136 equally between B and C due to symmetry, leaves 136/2 = 68° for C
Answer:
64 cubic inch=4 inch
Step-by-step explanation:
To calculate the cubic inches in a easy way, we can convert all the unit to inches first, then, multiply length, width and height values together, this will give you the volume of the cube.
Answer:
19
Step-by-step explanation:
you begin with the innermost parentheses, which is 9-6
9-6=3
you then move to the brackets, which has the 2 and tour answer from before, 3. You multiply 2 and 3 and get 6. You then add the 6 plus the 13 on the outside.
13+6=19
