Shania and Pedro are discussing whether it is always possible to solve a right triangle, given enough information, without using
Makovka662 [10]

Answer: Shania is correct.

Step-by-step explanation:

For a right angled triangle, given two sides and an angle, we can use the sine rule or the various trigonometry identities to solve the triangle;

a/sin A = b/sinB

and

sin (angle) = opposite side/hypotenuse

cos (angle) = adjacent side/hypotenuse

tan (angle) = opposite/ adjacent

assuming a is the opposite side of angle A and b is also opposite of angle B

Otherwise, the only way to solve a triangle given two sides only is by the use of the Pythagoras theorem.

Hence, Shania is correct.

PLEASE HELP WITH THESE LIMITS ASAP!
marusya05 [52]

Answer:

  • 4
  • -4

Step-by-step explanation:

When you follow the curve from the left toward x=2, you wind up at the open circle at (2, 4). The limit from that direction is 4.

When you follow the curve from the right toward x=2, you wind up at the open circle at (2, -4). The limit from that direction is -4.

\lim\limits_{x \to 2^-}{f(x)} =4\\\\\lim\limits_{x \to 2^+}{f(x)} =-4

Colton and Gage were building a castle together. Colton was 5 times as fast at building the castle than Gage. If it takes 120 bl
ira [324]

Answer:

100 blocks.

Step-by-step explanation:

Let x represent number of blocks built by Gage.

We have been given that Colton was 5 times as fast at building the castle than Gage, so number of blocks built by Colton would be 5x.

We are also told that it takes 120 blocks to build the castle. Since Colton and Gage were building a castle together, so number of blocks built by both will be equal to 120.

x+5x=120

6x=120

\frac{6x}{6}=\frac{120}{6}

x=20

Number of blocks built by Colton: 5x=5\cdot 20=100.

Therefore, Colton had build 100 blocks.

Please Help!! [ tough geometry question :( ]
kaheart [24]

Answer: 133^{\circ}

Step-by-step explanation:

Opposite angles of a cyclic quadrilateral are supplementary, so:

4x+5+x+15=180\\\\5x+20=180\\\\5x=160\\\\x=32

This means that m\angle A=4(32)+5=\boxed{133^{\circ}}
