Answer:

340mm

Step-by-step explanation:

Area = P × (L ÷ 2) - L × L

But in this case, L for length will be represented by the base which is 34 mm.

P × (L ÷ 2) - L × L

P = 88 mm

88 × 34 ÷ 2 - 34 x 34

= 340 mm

Question 26 please. will give brainliest
shusha [124]

Answer:

To find how tall he was at the end of the school year, you add his height at the beginning of the year and during the school year. First you should just add the inches.

2 1/4 + 7/8

The common denominator is 8.

2 2/8 + 7/8

2 9/8

3 1/8

Put back in the 5 ft.

So, Jerry was 5ft and 3 1/8 inches at the end of the school year.

Hope this helped! :)

Matt is standing on top of a cliff 305 feet above a lake the measurement of the angle of depression to a boat on the lake is 42
sashaice [31]

Answer:

The boat is approximately 338.74 feet from the base of the cliff. If the problem suggests rounding to the nearest whole number, you should use 339 ft.

Step-by-step explanation:

Let's draw the right angle triangle associated with the problem (see attached image). Notice that the 305 ft height corresponds to the "opposite side" to the given acute angle of 42^o, and that the distance we need to find is the "adjacent" side to the given acute angle. Therefore, the appropriate trigonometric function to use is the "tangent", given that from it we can solve for the unknown adjacent side "x":

tan(42^o)=\frac{opposite}{adjacent} \\tan(42^o)=\frac{305}{x}\\x=\frac{305}{tan(42^o)}\\ x=338.74\,\, ft
