Answer:
13
Step-by-step explanation:
Angles ( 12x - 29 ) and ( 4x + 1 ) are co - interior angles.
Sum of co - interior angles is supplementary.
12x - 29 + 4x + 1 = 180
12x + 4x - 29 + 1 = 180
16x - 28 = 180
16x = 180 + 28
16x = 208
x = 208 / 16
x = 13
<h2>answer:</h2>
13/8
alternative forms:
1 5/8, 1.625
<h2>step-by-step explanation: </h2>
2 1/8-1/2
multiply 2 and 8
16+1/8-1/2
add 16 to 1
17/8-1/2
least common multiple of 8 and 2 is 8. Convert 17/8=2.125 and 1/2=0.5 to fractions with denominator 8.
17/8-4/8
subtract numerators and put denominators as only one 8.
--------
13/8

The area of the triangle is found as 12 unit².
<h3>What is defined as the triangle?</h3>
A triangle is a three-sided polygon with three sides that closes a space.
- The three sides are formed by lines, line segments, or rays (in just about any combination).
- Three vertices, or corners, are formed if three sides form or meet.
- A triangle's height or altitude is calculated by drawing a perpendicular line through one side to the opposite angle.
- The base is the side with which the altitude intersects wherever it is built.
The formula for the area of the triangle is;
Area of triangle= ½ × base × height
The base is given as 6 units and the height is 4 units. (count 1 column of graph as 1 unit).
Put the values in formula.
Area of triangle = ½(6)(4)
Area of triangle = 12 unit.²
Therefore, the area of the triangle is found as 12 unit.²

<span>Answer:
17576=pir^2h
the amount of material M=2pir^2 +2pirh
M=2pir^2+2pir(17576/pir^2)
DrM= 4pir- 35152/r^2
DrM=0
0=4pir- 35152/r^2
r=(13*2^(2/3))/pi^(1/3)
17576=pi((13*2^(2/3))/pi^(1/3))^2)h
17576/(pi((13*2^(2/3))/pi^(1/3))^2))=h
r=14.0901
h=28.1801
