Answer:
41.802 feet
Step-by-step explanation:
Given that a 92 ft path cuts diagonally from Mateo St. to Cove St. It makes an angle of 68° with Cove St. and an angle of 34° with Mateo St.
We can visualize a triangle formed by the three streets One side is 92 feet.
Angle opposite 92 feet =
Let x be length of Cove st and y length of Mateo st.
Using sine angle for triangles,
Simplify to get
x=52.595
y=87.207

Answer:
-1
Step-by-step explanation:
We need to find the value of tan² 70° -sec² 70°.
We know that,
...(1)
We can write the given expression as :
tan² 70° -sec² 70° = -(-tan² 70° +sec² 70°)
=-(sec² 70°-tan² 70°)
Using identity (1)
=-(1)
= -1
Hence, the value of the given expression is -1.
Answer:
t(99)= -2.89
Step-by-step explanation:
-To places after the decimal point is equivalent to rounding off to the nearest hundredth.
-To round off to the nearest hundredth, we check the thousandths digit:
- If the thousandths digit is less than5, we round down to the previous hundredth.
- If the thousandths digit is greater than 4, we round up to the next hundredth:
Hence,
