LuckyWell [14K]3 years ago
4 0

Answer/Step-by-step explanation:

Statement 1: \overline{AD} = \overline{RC}

Reason 1: Given

Statement 2: <A ≅ <R

Reason 2: Given

Statement 3: <AMD ≅ <RMC

Reason 3: vertical angles

Both angels are vertical angles. Vertical angles are congruent to each other. Therefore, <AMD ≅ <RMC.

Statement 4: ∆MAD ≅ ∆MRC

Reason 4: AAS Congruence Theorem

Two angles and a non-included side in ∆MAD are congruent to corresponding two angles and a non-included side in ∆MRC. Based on the AAS Congruence Theorem, both triangles are congruent.

What is the value of y ?
ArbitrLikvidat [17]

Answer:

6

Step-by-step explanation:

Draw line segments ST and RQ. Triangle RUQ and SUT are similar, because they are in a circle. Now, you use similar triangles to get that QU/UT=RU/SU so 2 = 12/SU so SU = 6, or y = 6.


Note: This is generealized by the Power of a Point, which states that if you have two chords that intersect, then you can do the same thing and it will show that QU*SU=RU*TU. (You can change the variables but the similar triangles stay the same).

Find the values of XYNZ to the nearest integer
katen-ka-za [31]

Answer:

Part 1) The measure of x is 23°

Part 2) The value of y is y=5\ units

Part 3) The value of z is z=12\ units

Step-by-step explanation:

step 1

Find the value of x

we know that

x+67\°=90\° ------> by complementary angles

x=90\°-67\°=23\°

step 2

Find the value of y

In the right triangle of the figure

cos(67\°)=\frac{y}{13} -----> adjacent side angle of 67 degrees divided by the hypotenuse

y=(13)cos(67\°)=5\ units

step 3

Find the value of z

In the right triangle of the figure

sin(67\°)=\frac{z}{13} -----> opposite side angle of 67 degrees divided by the hypotenuse

z=(13)sin(67\°)=12\ units
