Ineed to find the measure of each angle indicated

We shall use the mnemonics SOH-CAH-TOA to find the missing angles.

SOH- means sine ratio is

CAH- means cosine ratio is

TOA- means tangent ratio is

11) From the given right-angle triangle,the side length adjacent to is 11 units.

The opposite side  is 8 units.

We use the tangent ratio to obtain:

to the nearest tenth.

12) From the given right-angle triangle,the side length adjacent to is 7 units.

The opposite side  is 13 units.

We use the tangent ratio to obtain:

to the nearest tenth.

13) From the given right-angle triangle,the side length adjacent to is 8 units.

The opposite side  is 11 units.

We use the tangent ratio to obtain:

to the nearest tenth.

14. This time we were given the hypotenuse to be 9.7 units and the opposite side of the right-angle triangle is 7 units.

We use the sine ratio to obtain:

15. For question 15; we the hypotenuse to be 7 units and the adjacent side is 4 units.

We use the cosine ratio to get;

to the nearest tenth.

16) From the given right-angle triangle,the side length adjacent to is 13 units.

The opposite side  is 12 units.

We use the tangent ratio to obtain:

to the nearest tenth.

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:

hi,

i'm 75% sure the answer is 1,1 to both lines.

have a great day
