Answer:

70.4 meters

Step-by-step explanation:

A to B: 40²+10²=c² = 1600+100=c² = 1700=c² = c=√1700 = 41.23

B to C: 25²+15²=c² = 625+225=c² = 850=c² = c=√850 = 29.15

41.23+29.15=70.38

In the triangle below, the value of a is 12.6.<br><br> True<br><br> False
aev [14]

Answer:

True

Step-by-step explanation:

Formula

Tan(x) = opposite / adjacent

Givens

x = 42

adjacent = 14

opposite = ?

Solution

Tan(42) = opp/14                     Find tan(42)

Tan(42) = 0.900404

0.900404 = opp/ 14                Multiply both sides by 14

14 * 0.900404 = opp/14 * 14   Simplify the left

12.6 rounded  = opp

a = 12.6

Delaware was the first state to enter the Union and Hawaii was the 50th. If we order the positions of entry for the rest of the
Anna71 [15]

Answer:

State A was the <u>12th</u> state to enter the Union. State B was the <u>11th</u> state to enter the Union.

Step-by-step explanation:

Let's call x to the order-of-entry of State B, therefore the order-of-entry of State A is x+1. Given that he product of their order-of-entry numbers is 132:

x*(x+1) = 132

x² + x - 132 = 0

Using quadratic formula:

x = \frac{-b \pm \sqrt{b^2 -4(a)(c)}}{2(a)}

x = \frac{-1 \pm \sqrt{1^2 -4(1)(-132)}}{2(1)}

x = \frac{-1 \pm 23}{2}

x_1 = \frac{-1 + 23}{2}

x_1 = 11

x_2 = \frac{-1 - 23}{2}

x_2 = -12

The negative solution has no sense in the context of our problem, then the solution is x = 11.
