Problem 1

<h3>Answer: choice B) They are supplementary angles</h3>

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

Explanation:

The two angles combine to form a straight angle (which is 180 degrees). Another term for these angles is "linear pair" since they form a straight line.

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

Problem 2

<h3>Answer: choice B) x = 7</h3>

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

Explanation:

The diagonal is never used in this problem. For any rhombus, the four exterior sides are always the same length.

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

Problem 3

<h3>Answer: Choice D) 62 degrees</h3>

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

Explanation:

We use the angle addition postulate. This allows us to combine angles BAC and CAD to form angle BAD.

(angle BAC)+(angle CAD) = angle BAD

30 + x = 92

x = 92-30

x = 62

angle CAD = 62

If the atmospheric pressure at Mangamaunu Beach is 1000 millibars and we assume the general guideline that atmospheric pressure

Mashutka [201]

Answer:

Atmospheric Pressure = 739.2 millibars

Step-by-step explanation:

To answer this question one should assume that Mangamaunu Beach is at sea level ( altitude = 0 m) and that the summit of Manakau is at 2608 meters.

The change in atmospheric pressure with altitude in the first 5 km can be roughly represented by a linear relationship with slope "m" as follows

$(500-1000) = m(5000 - 0)\\m = -0.10$

Giving the following equation:

$(Pressure - 1000) = -0.10Height$

Applying for Height = 2608 m

$Pressure = -0.10(2608) + 1000\\Pressure = 739.2 millibars$

If we apply the Pythagorean Theorem to the Egyptian knots we can see that 3^2 + 4^2 = 5^23 2 +4 2 =5 2 . Which of the sets of th

pantera1 [17]

Answer:

B) { 51, 149, 140 }

C) { 16, 63, 65 }

Step-by-step explanation:

We need to choose Pythagoras theorem formula

$c^2=a^2+b^2$

now, we can verify each options

option-A:

a=1

b=1

c=1

now, we can verify formula

$1^2=1^2+1^2$

$1=2$

We can see that left side is not equal to right side

so, this is FALSE

option-B

a=51

b=140

c=149

now, we can verify formula

$149^2=51^2+140^2$

$22201=22201$

We can see that left side is equal to right side

so, this is TRUE

option-C

a=16

b=63

c=65

now, we can verify formula

$65^2=16^2+63^2$

$4225=4225$

We can see that left side is equal to right side

so, this is TRUE

option-D:

a=6

b=8

c=11

now, we can verify formula

$11^2=6^2+8^2$

$121=100$

We can see that left side is not equal to right side

so, this is FALSE
