Answer:

Step-by-step explanation:
sin60° = 
tan60° = 
tan45° = 1
cos45° = 
(2sin60°)(3tan60°) - (4tan45°)(2cos45°)
now substitute the values of each trigonometrical angles






Answer:
it is true
Step-by-step explanation:
If two angles and the non-included side of one triangle are equal to the corresponding angles and side of another triangle, the triangles are congruent.
10/4 + 1/3 = 17/6
step 1: reduce the fraction with 2:
5/2 + 1/3
step 2: write all numerators above the common denominator 6:
15 + 2/ 6
step 3: add the numbers:
17/6
