A.) {4,.8,.16,.032,...}
Begin with 4 and multiply by 0.2, the ratio, to obtain successive term.
First, solve for each of the angles. Since it is a right triangle, one of the angles is 90 degrees. Knowing that the sum of the angles of a triangle are always equal to 180 degrees, you can write an equation for the triangle.
Angle1+ angle2+angle3=180.
Which means that 90+(x+15)+2x=180.
After finding the value of x, which is 25 in this case, solve for each angle.
X+15=25+15=40.
2x=25*2= 50
The value of the smallest angle is 40 degrees.
Step-by-step explanation:
3×3=9. 3 faces so 9×3=27
10×3=30. 4 faces so 30×4=120
6×3=18. 2 faces so 18×2= 36
15×3=45. 3 faces so 45×3= 135
120+135=255
36+27=63
255+63=318
answer =318
Answer:
Step-by-step explanation:
when solving and equation with a variable, you must work backwards and do the opposite of the equation
sooo… you must subtract 4 (opposite of +4 is -4)
x=12
