Step-by-step explanation:

As,

x + 14 + 3x = 90 [Complementary Angles]

=> 4x = 90 - 14

=> 4x = 76

$= > x = \frac{76}{4}$

=> x = 19

Hence,

<1 = x + 14°

 = 19 + 14 = 33°

<2 = 3x

 = 3 × 19° = 57°

How can you use 4×7 to find 8×7

Natasha_Volkova [10]

If you think about it, 4x7 is half of 8x7 (If you multiply 4, 7, and 2, you get 8x7). So really you can just multiply 4x7 by 2 and you will get 8x7!

grandymaker [24]

we are given

A woman walks due east on the deck of a ship at 4 mi/h.

the ship is moving south at a speed of 24 mi/h

so, firstly, we will draw diagram

so, we have

$OW=4$

$OS=24$

now, we can use Pythagoras theorem

$SW^2=OS^2+OW^2$

now, we can plug values

and we get

$SW^2=24^2+4^2$

$SW=24.33$

so,

the speed of the woman relative to the surface of the water is 24.33 mi/h .......Answer

What is the area of the yellow triangle?

lesantik [10]

I can't see pictures, but to find the area of a triangle, you multiply the dimensions, as you would a rectangle, but divide the area by 2.

For example, the dimensions of a triangle are 4 and 6.

Multiply the two.

4x6=24.

But don't stop there. Divide 24 by 2.

24/2=12.

So the area of the example triangle is 12.
