I'm guessing the total amount of degrees is 360 degrees.

67 + 130 + 72 = 269

360 - 269 = 91

Answer = 91°

Hope this helped☺☺

72+67+130=269
360-269= 91
hope that helps

Answer:

4 and 12

Step-by-step explanation:

Given

f(x) = 4 $(3)^{x}$ , then

f(0) = 4 $(3)^{0}$ = 4 × 1 = 4 [ $a^{0}$ = 1 ]

f(1) = 4 $(3)^{1}$ = 4 × 3 = 12

Magnitude of vector V =√(3²+7²) = √58

Hence: U= -3/√58 - 7/√58

OR multiply numerator and denominator by √58

U = - (3√58)/58 i - (7√58)/58 j
