Answer:

134

Step-by-step explanation:

There's 2 blue arrows where 39 is, and the same arrows where 4x+7 are. This means that they are the same length. So, 4x+7 = 39. Perimeter means you add, so 28+28+39+39 = 134.

La of sine:

sinC/c = sinB/b==> sin  37°/8 = sin B/12 ==> sin B = 0.903


arcsinB or sin⁻¹ B = 64.5°, & sin (B°) = sin (180° - B°), then

sin(64.5) = sin(180°-64.5°) ==> B = 64.5° or 115.5°

PLEASE help, I don’t understand this in the slightest and I’m about to snap my own neck ahaaa :((
Margarita [4]

Answer:

Calm down, it's simple. Take 180 degrees and subtract M-2 from it. (180-125: 55) A is 55. Than you can fill in A. Repeat with other angles, looking for a pair that forms 180 degrees. Take the value you know and use it to calculate the other one. Take your time.

Answer:

3x - 14

Step-by-step explanation:

Perimeter = 2(length+width)

= 2[(½X-7) + (x)]

= 2[½x + x - 7]

= 2[1.5x - 7]

= 3x - 14
