Answer:
The three questions about the given triangle has been answered below.
Step-by-step explanation:
We are given a right angled triangle whose sides are of length 20, 21 and 29.
<u>(1)</u> sin(B) = 
= 
= 0.72
<u>(2)</u> sin(A) = 
sin(A) = 0.689
∠CAB = 
∠CAB = 43.551°
<u>(3)</u> We suppose that cosA < sinA and we haveto find which all angles will satisfy this condition.For this the angle A should be greater than 45°.
From the given options the angles that satisfy this are 55 , 66 and 75.
45 is not included as then sinA = cosA and that condition is not there.
Answer:
Congruence is a relationship of shapes and sizes, such as segments, triangles, geometrical figures, while equality is a relationship of sizes, such as lengths, widths, heights.
Congruence deals with objects while equality deals with numbers. You wont say that two shapes are equal or two numbers are congruent.
Step-by-step explanation:
Well 10 molasses cookies and total number is 18 so the ratio is 10:18 then to simplify that it will be dividing by 2 so 5:9 is the answer or C
Answer:
y=4x+7
Step-by-step explanation:
4x+y=7
Isolate one of the variables
4x-4x+y=7+4x
y=7+4x
slope is 4 (Up 4, Right 1)
y-intercept is (0,7)
