Answer:
46°
Step-by-step explanation:
Since the 3 sides are given we can use any of the 3 trig. ratios to solve.
Using the tangent ratio in the right triangle
tan ? = = , thus
? = ( ) ≈ 46° ( to the nearest degree )
Answer:
D. 65°
Step-by-step explanation:
it's a isosceles triangle so the angles of same length sides has same measure.
Answer:
54x^6 - 5
Step-by-step explanation:
Answer:
24 cm
Step-by-step explanation:
since the two triangles are similar,
10cm/20cm = 36cm _ h/h
Answer: Yes, it's true.
Step-by-step explanation:
The first step is to convert the mixed number to a fraction. The procedure for this is:
- Multiply the whole number 1 by the denominator 5.
- Add the product obtained and the numerator 2 (This will be the numerator of the fraction).
- The denominator does not change. It will be 5.
Then:
Rewrite the equation:
Notice that the denominators on the left side are 4 and 5 and the denominator on the right side are also 4 and 5.
Then, the Least Common Denominator (LCD) on both sides is:
Now we can solve the subtraction on the left side of the equation and the addition on the righ side:
Therefore:
(IT'S TRUE)
