Consider the right triangle shown below. Suppose the hypotenuse of this right triangle is r=7 cm long.

Suppose that sin(θ)=0.629.

y is how many times as large as r?
 _times as large   

What is the value of y?
y=

Suppose that cos(θ)=0.778.

x is how many times as large as r?
 _times as large   

What is the value of x?
x=

​

Which is a logical conclusion based on the given information? a. figure abcd is a rhombus by the definition of a rhombus. b. segment ac is congruent to segment dc by cpctc. c. angle acb is congruent to angle adc by the angle-side-angle theorem. d. triangle acd is congruent to triangle cab by the hypotenuse-leg theorem.
