Answer:
<u>If P is 30 units and l is 10 units, w is 5 units</u>
Step-by-step explanation:
1. Let's check the information given to resolve the question:
P = 2l + 2w
If P is 30 units and l is 10 units, w is units
2. Replacing with the values:
P = 2l + 2w
30 = 2 (10) + 2w
30 = 20 + 2w
-2w = 20 -30 (Subtracting 2w and - 30 to both sides)
-2w = - 10
2w = 10 (Multiplying by - 1 at both sides)
<u>w = 5 (Dividing by 2 at both sides)</u>
<u>If P is 30 units and l is 10 units, w is 5 units</u>

Answer:
8 CM
Step-by-step explanation:
(Hypotenuse)²=(Base)²+(Height)²
10²=X+6².
100=X+36
100-36=X ( by transposition method )
√64=X
8=X
Answer:
Step-by-step explanation:
<u>Given </u><u>:</u><u>-</u>
- The slope of the line in the graph is 4.
And we need to find the equation of the line. On looking at the graph we see that , it cuts y axis at (0,3) .So the y Intercept of the equation is 3 .
<u>Slope</u><u> Intercept</u><u> Form</u><u> </u><u>:</u><u>-</u><u> </u>
<u>Substituting</u><u> the</u><u> respective</u><u> values</u><u> </u><u>:</u><u>-</u><u> </u>
<u>Hence</u><u> the</u><u> </u><u>equation</u><u> of</u><u> </u><u>line </u><u>is </u><u>y </u><u>=</u><u> </u><u>4</u><u>x</u><u> </u><u>+</u><u> </u><u>3 </u>
Here in this question, we are to solve for x and get the measure of Angle A
Mathematically,
∠A = ∠B
The reason for this is because both are corresponding angles and corresponding angles are equal.
Since they are equal in value, we can equate the given expressions for each of the two angles
Thus;
7x + 40 = 3x + 112
Let us collect like terms
7x-3x = 112 - 40
4x = 72
x = 72/4
x = 18
But the question asks to get the value of ∠A
From the questionn, we are told that ∠A = 7x + 40
To get the value of ∠A, we need to substitute x
∠A = 7(18) + 40
∠A = 126 + 40
∠A = 166
∠A = 166 and x = 18
