Divide the sum of 3/8 and -5/12 by the reciprocal of 16/27 x(-15)/8

Travka [436]

Answer:

First find the sum of 3/8 and -5/12

That is

3/8 - 5/12

First find the common denominator

The common denominator is 24

We get

3/8 - 5/12 = 3(3) - 5(2) / 24

= 9 - 10 / 24

= - 1 / 24

Next find the product of 16/27 x(-15)/8

That's

16/27 × -15/8

= -10/9

Next reverse -10/9

Which is -9/10

Next we divide it by = -1 /24

so we get

-1/24 ÷ -9/10

Change the sign to (×) and reverse the second fraction

We get

-1/24 × -10/9

= 5 / 108

Hope this helps

Answer:

21. ΔUYZ Obtuse

22. ΔBCD Right or Rectangle

23. ΔADB Acute

24. ΔUXZ Acute

25. ΔUWZ Right or Rectangle

26. ΔUXY Equiangular and acute

Step-by-step explanation:

We need to classify each triangle by its angles.

Acute: They have 3 acute angles (less than 90 degrees).

Rectangle: The inner angle A is straight (90 degrees) and the other 2 angles are sharp. The sides that form the right angle are called legs (c and b), the other side hypotenuse.

Obtuse: The inner angle A is obtuse (more than 90 degrees). The other 2 angles are acute.

ΔUYZ Obtuse The inner angle Y is obtuse (more than 90°).

ΔBCD Right or Rectangle The inner angle C is straight (90°).

ΔADB Acute It has 3 acute angles (less than 90°).

ΔUXZ Acute It has 3 acute angles (less than 90°).

ΔUWZ Right or Rectangle The inner angle W is straight (90°).

ΔUXY Equiangular and acute Which means all the inner angles are equal (60°).
