HEY YOU!! PLEASE I NEED HELPPP<br><br> find angle BAC and angle FAB
serious [3.7K]

Answer:

m∠BAC = 105°

m∠FAB = 75°

Step-by-step explanation:

By using the property of an exterior angle of a triangle,

Measure of an exterior angle is equal to the sum of opposite two angles of a triangle.

From the triangle given in the picture,

m∠ABC + m∠BCA + m∠CAB = 180°

(13x - 3)° = (3x + 2)° + 55°

13x - 3 = 3x + 57

13x - 3x = 57 + 3

10x = 60

x = 6

m∠FAB = (13x - 3)° = 75°

m∠ABC = (3x + 2)° = 20°

Since, ∠BAC and ∠FAB are the linear pair of angles,

m∠BAC + m∠FAB = 180°

m∠BAC + 75° = 180°

m∠BAC = 180° - 75° = 105°

Evaluate the expression 3 4/5x-2 1/2 for x =-10
lyudmila [28]

Answer:

The value of given expression for x = - 10  is - 81

Step-by-step explanation:

Given expression as :

3 \frac{4}{5}x - 2 \frac{1}{2}

Or, 3 +  \frac{4}{5}x  - 2 -  \frac{1}{2}

Or,  \frac{19}{5}x -  \frac{5}{2}

or,  \frac{38 x - 25}{5}

Now for  x = - 10

\frac{38\times (- 10)  - 25}{5}

Or, {38\times (- 2)  - 5}

∴ - 76 - 5

Or, - 81

Hence The value of given expression for x = - 10  is - 81  Answer
