In the right triangle shown, AC = BCAC=BCA, C, equals, B, C and AB = 6AB=6A, B, equals, 6.

alexandr402 [8]

Answer:

$|AC|=|BC|=3\sqrt{2}$

Step-by-step explanation:

In a right triangle, the hypotenuse is always the longest side. Since AC = BC, AB is the Hypotenuse.

Using Pythagoras theorem

$|AB|=6,|AC|=|BC|\\|AB|^2=|AC|^2+|BC|^2\\6^2=2|AC|^2\\36=2|AC|^2\\18=|AC|^2\\|AC|=\sqrt{18}=3\sqrt{2} \\Therefore, |AC|=|BC|=3\sqrt{2}$

The sum of the measures of the interior angles of a convex polygon is 1800 degrees? How many sides does the

AVprozaik [17]

Answer:

12 sides

Step-by-step explanation:

Given

Sum of interior angle = 1800 degrees

Required

Number of sides of the polygon

The sum of interior of a convex polygon is calculated using the following formula:

Sum = (n - 2) * 180

Where n is the number of sides of the polygon.

By substituting 1800 for Sum, we have

$1800 = (n - 2) * 180$

Divide through by 180

$\frac{1800}{180} = \frac{(n - 2) * 180}{180}$

$10 = n - 2$

Add 2 to both sides

$10 + 2 = n - 2 + 2$

$12 = n$

Re order

$n = 12$

Hence, the number of sides of the polygon is 12

yanalaym [24]

Answer:It's an arithmetic sequence with a common difference, d, = 4

A1 = 8

A2 = 8+4 = 12

A3 = 12+4 = 16 = 8+4(3-1) = 8+4(2) = 8+8

AN = A1 + d(N-1)

AN = 8 +4(N-1) = the Nth term in the sequence

Answer:

D. 285

Step-by-step explanation:
