In triangle ABC A-B= 15 degree, B-C= 30 degree find A,B,C

Mathematics
1 answer:
larisa86 [58]4 years ago
4 0

Answer:

A=80 , B=65, C=35

Step-by-step explanation:

A-B=15 ⇒A=B+15

B-C=30⇒-C=30-B ⇒C=B-30

the sum of angle of a triangle = 180

A+B+C=180 ( substitute A and C)

B+15+B+B-30=180

3B-15=180

3B=180+15

B=195/3=65

C=B-30 ⇒ C=65-30=35

A=B+15=65+15=80

check : A+B+C=180

             80+65+35=180 ( correct)

The height of a parallelogram is one-third its base. If the area of the parallelogram is 363 square inches, find its base and he
kipiarov [429]

Answer:

Height = 11 inches

Base = 33 inches

Step-by-step explanation:

In this question, we are asked to find the height and base of a parallelogram given the area of the parallelogram.

From the question, we are told that height is 1/3 of base. This means that base is 3 times the height

So if we represent the height with variable h, then the base is 3h

Mathematically the area of a parallelogram can be calculated by the formula

A = bh

Thus ,

363 = h * 3h

3h^2 = 363

divide through by 3

h^2 = 121

h = √121

h = 11 inches

since b = 3h , then b = 3 * 11 = 33 inches

If the sum of three consecutive integers is 36, what is the smallest of these integers?
DedPeter [7]
Let the three consecutive equals:
x, x+1, x+2

sum:
x+(x+1)+(x+2) = 36
3x + 3 = 36
x+1 = 36/3
x+1 = 12
x=12-1
x=11

How is multiplying and dividing numbers in scientific notation different from adding and subtracting numbers in scientific notat
cupoosta [38]

Answer:

multiple and divide are depending on the powers ( sometimes the numbers before the scientific n.)

If the power neg- , it's going down

like this 10^-5 = 1/10^5

If the power pos+ , it's the same idea but different in signs .

Adding and subtracting are depending on numbers ( If the scientific n. is the same number) .

for example:

3x10^5 + 4x10^5 = (3+4)x10^5 = 7x10^5
