You can use the cos Ф = base / hypotenuse.
 In this case, you have h = 42/cos 35 (approx. 0.819)
h = 42/0.819 = 51.3

To the nearest whole number, the length of the ladder is 51 feet.

<h3>Answer:  133</h3>

=============================================================

Explanation:

The quickest way to get this answer is to add the angles given to get 87+46 = 133

This is through the use of the remote interior angle theorem.

Note how the angles 87 and 46 are interior, or inside the triangle. And also, they are not adjacent to the exterior angle we want to find. So that's where the "remote" portion comes in.

----------------

The slightly longer method involves letting x be the measure of the missing interior angle of the triangle.

The three interior angles add to 180

87+46+x = 180

133+x = 180

x = 180 - 133

x = 47

The missing interior angle of the triangle is 47 degrees.

Angle 1 is adjacent and supplementary to this 47 degree angle, so,

(angle1)+(47) = 180

angle1 = 180-47

angle1 = 133 degrees

This example helps confirm that the remote interior angle theorem is correct.

A quadrilateral has 4 vertices. If you add two bases, its like adding two vertices. 4+2=6. A figure that has 6 vertices is a hexagon, so the answer is hexagon.

64 is 4 times the difference between Sarah's age, a, and 44. Assume Sarah is older than 44.
muminat

Answer:

60 years old

Step-by-step explanation:

64=4(a-44)

64=4a-176

64+176=4a

240=4a

4a=240

a=240/4

a=60 years old
