Answer: 96°
Step-by-step explanation:
Sum of angles of a triangle = 180°
3 + 8 + 4 = 15
The biggest angle is 8/15 * 180 = 96°
Answer:
19/2 or 9.5
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4(x−5)(2)=36
8x+−40=36(Distribute)
8x−40=36
Step 2: Add 40 to both sides.
8x−40+40=36+40
8x=76
Step 3: Divide both sides by 8.
8x/8=76/8
x=19/2
The unknown number expressed as a mixed fraction is 11 19/20
Let the unknown number be "x"
The sum of the number and 1.75 is expressed as x + 1.75
Half the sum of a number and 1.75 is 1/2(x+1.75)
Equating the result to -5.1 wil give:
1/2(x+1.75) = -5.1
Solve the resulting equation
x + 1.75 = 2(-5.1)
x + 1.75 = -10.2
x = -10.2 - 1.75
x = 11.95
x = 1195/100
x = 11 95/100
Hence the unknown number expressed as a mixed fraction is 11 19/20
