4. An isosceles triangle has sides that measure 7cm and 15cm. Find the third side of the

Advocard [28]

Answer:

Third side is 15cm. Perimeter is 37cm.

Step-by-step explanation:

In a triangle sum of two sides is always greater than third side. Two sides of a isosceles triangle are equal.

So if the third side is 7cm

7+7=14cm which is less than 15 cm.

hence third side is 15 cm as

15+15=30cm which is greater than 7cm

15+7=22cm which is greater than 12cm

then

perimeter=15+7+15=37cm

$\frac{1}{R} = \frac{1}{8} + \frac{1}{12} \\$

$\frac{1}{R} = \frac{1 \times 3}{8 \times 3} + \frac{1 \times 2}{12 \times 2} \\$

$\frac{1}{R} = \frac{3}{24} + \frac{2}{24} \\$

$\frac{1}{R} = \frac{3 + 2}{24} \\$

$\frac{1}{R} = \frac{5}{24} \\$

Inverse both sides

$\frac{R}{1} = \frac{24}{5} \\$

$R = \frac{24 \times 2}{5 \times 2} \\$

$R = \frac{48}{10} \\$

$R = 4.8 \: \: Ω$

In a triangle, the measure of the first angle is twice the measure of the second angle. The measure of the third angle is 64 deg

Xelga [282]

Argument
Let the second angle = x
Let the first angle = 2x
Let the third angle = x + 64

Substitute and Solve
x + 2x + x + 64 = 180 Collect the like terms on the left.
4x + 64 = 180 Subtract 64 from both sides.
4x = 180 - 64
4x = 116 Divide by 4
x = 116 / 4
x = 29

Conclusion
x = 29
2x = 58
x + 64 = 93 I'm leaving you with the problem of checking this out.

Answer
The first angle = 58
The second angle = 29
The Third angle = 93
