Ok so the lines with two triangles are parralel to eachother. The lines with one are parallel to eachother.
The angle of 109° and angle of z° equal eachother. Z=109°
Since 109°, 33° and y° form a triangle, the sum of the angles will equal 180. Add 109 and 33 to get 142. Subtract 142 from 180 to get y°=38°.
Since z=109, this means that the triangle is congruent with the other. Since the congruent triangles are in a rhombus, then the angles are flipped. Thus, angle x =33°.
z=109°
y=38°
x=33°
False
Exponents should not be simplified.
1/3 of an hour= 60mins/3
= 20 mins
1/2an hour= 60mins/2
= 30 mins
30+20 = 50 minutes total
<u>Answer</u>
12
<u>Explanation</u>
Cosine is the ratio of adjacent to hypotenuse.
So, in this case b is the adjacent and 13 is the hypotenuse.
cos22.6 = b/13
b = 13×cos22.6
= 13×0.923879532
=12.010
To the nearest whole number the answer is 12.
