Answer:

h=7

Step-by-step explanation:

$h+(-3)=4$

may be rewritten as

$h-3=4$

as adding a negative is the same as subtracting a positive.

To solve, add 3 to both sides.

$h-3=4\\h=7$

an observer on a cliff 1200 feet above sea level sights two ships due East. The angle of depression to the shops are 48° and 33°

ziro4ka [17]

See the attached figure to better understand the problem

we know that
in the triangle ABC
tan 48°=AB/AC--------> AC=AB/tan48°------> 1200/tan 48°------> 1080.48 ft

in the triangle ABD
tan 33°=AB/AD---------> AD=AB/tan 33°-----> 1200/tan 33°------> 1847.88 ft

<span>the distance between the ships is AD-AC---> 1847.88-1080.48----> 767.4 ft

the answer is
</span>the distance between the ships is 767.4 ft<span>

Find the area of each triangle with the given heights and bases. a. h = 6 inches; b = 10 inches b. h = 9 centimeters; b = 4 cent

dsp73

The area of triangles is a. 30 inches², b.18 inches², and c. 130 yards² for the given triangles.

<h3>What is a triangle?</h3>

A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices.

In a triangle, the sum of all three angles is 180°

Triangle is a very common figure to deal with our daily life for example in our daily life to measure the height of any tower then there is a huge application of the right angle triangle.

Area of a triangle = (1/2) × height × base

a) Given

h = 6 inches; b = 10 inches

Area = 6 × 10/2 = 30 inches².

b) Given

h = 9 centimeters; b = 4 centimeters

Area = 9 × 4/2 = 18 inches².

c) Given

h = 13 yards; b = 20 yards

Area = 13 × 20/2 = 130 yards².

Hence the area of triangles is a. 30 inches², b.18 inches², and c. 130 yards² .
