Answer:

x = 102 , y = 35

Step-by-step explanation:

x and 78 are same- side interior angles and sum to 180° , that is

x + 78 = 180 ( subtract 78 from both sides )

x = 102

x and 6y - 108 are vertically opposite angles and are congruent , so

6y - 108 = 102 ( add 108 to both sides )

6y = 210 ( divide both sides by 6 )

y = 35

Find AB<br> Round to the nearest tenth.
lianna [129]

Answer:4.1

Step-by-step explanation:

c=AB

C=26°

B=122°

b=8

Using sine rule

c/sinC = b/sinB

c/sin26=8/sin122

Sin26=0.4384

Sin122=0.8480

c/0.4384=8/0.8480

Cross multiply

c x 0.8480=8 x 0.4384

c x 0.8480=3.5072

Divide both sides by 0.8480

(c x 0.8480)/0.8480=3.5072/0.8480

c=4.1

Find the value of w-9 given that –3w+5 = 2
melamori03 [73]

Answer:

-8

Step-by-step explanation:

Solving for w given the equation, -3w +5 = 2:

-3w +5 = 2 \\ -3w +5 -5 = 2 -5 \\ -3w = -3 \\ \frac{-3w}{-3} = \frac{-3}{-3} \\ w = 1

Solving for w -9 when w = 1

1 -9 \\ -8
