When the terms do not have the same number or the other vaue, it must be given in your maths book,chapter related to fractions
Answer:
Volume of triangular pyramid = 2,090 inch³
Step-by-step explanation:
Given:
Side height of base = 19 inch
Side length of base = 22 inch
Height of triangular pyramid = 30 inch
Find:
Volume of triangular pyramid
Computation:
Area of triangular base = (1/2)(b)(h)
Area of triangular base = (1/2)(19)(22)
Area of triangular base = 209 inch²
Volume of triangular pyramid = (1/3)(A)(h)
Volume of triangular pyramid = (1/3)(209)(30)
Volume of triangular pyramid = 209 x 10
Volume of triangular pyramid = 2,090 inch³
Answer:
x=90° and y=35°
Step-by-step explanation:
to get x and y first you must find the middle angles based on the information you have so:
35+90+n=180° solve for n to get what the middle angles are (since they are vertical angles they are equal) so the middle angles are both 55 degrees
and then 180-x=that angle that is also on the line with x so we'll call it k
so k+55+y=180°
we can see that y equals 35* because I noticed that those are parallel lines on the outside of the triangle so 35* and y angles are congruent and y =35°
now 35+55+k=180°
solve for the angle next to x which we called k and it is 90°
so x=90° and y=35°
after all this math I realized that if they are parallel lines then we can just use that to figure it out so use the properties to find out that x=90° and y=35°
Hello from MrBillDoesMath!
Answer: x = +9
Discussion:
-59 = 3x -2 (7x -20) or
-59 = 3x - (2*7)x - 2 ( -20) or
-59 = 3x -14x + 40 or
-59 = -11x + 40. Subtract 40 from each side
-59 - 40 = -11x or
-99 = -11x
or x = + 9
Thank you,
MrB
