Answer:
81
Step-by-step explanation:
The definition of a square is a four sided figure that has 2 sets of parallels lines, 4 congruent sides, and 4 right angles. From that you can tell that one side of the square gives the measurement of all sides of the square.
Answer:
m∠1=118°
m∠2=62°
Step-by-step explanation:
Part A: They are supplementary angles, so
Simplify like terms,
We subtract 92,
Divide by 2,
Part B:
∠
because ∠2 is vertical to 2x+30.
Plug in 44 for x,
∠
Simplify,
∠
∠
° because it is a vertical angle to the 62° angle.
It would take about 40 seconds for the temperature to reach 70°C and 44 second to reach 74°C.

Linear equation</h3>
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the slope of the line and b is the y intercept.
Let y represent the temperature of the metal bar after x seconds, hence:
Since the metal bar has an initial temperature of 30°C, hence:
b = 30, also m = 1°C (increase), The equation becomes:
y = 1(x) + 30 = x + 30
To reach 70°C:
70 = x + 30
x = 40 seconds
To reach 74°C:
74 = x + 30
x = 44 seconds
It would take about 40 seconds for the temperature to reach 70°C and 44 second to reach 74°C.

Answer:
26.3 grams
Step-by-step explanation:
36% = 36/100 = 0.36
73 * 0.36 = 26.28 grams ≈ 26.3 grams
