Answer:

D = 127°

Step-by-step explanation:

We know that sum of all angles in a triangle is 180°.

Thus, the measure of third angle will be -

180 - (85 + 42)

180 - 127

= 53°

We also know that sum of adjacent angles is 180°. So,

D = 180° - third angle

D = 180° - 53°

D = 127°

Answer:

∠ D = 127°

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ D is an exterior angle of the triangle , then

∠ D = 85° + 42° = 127°

HELP PLEASE!! ASAP!!

densk [106]

Answer:

The estimated distance is 8.1cm.

The actual distance is 8.106cm.

Step-by-step explanation:

Given that the Pythogorean Theorem, c² = a² + b². Then substitute the following values into the formula :

${c}^{2} = {a}^{2} + {b}^{2}$

Let a = 5.1cm,

Let b = 6.3cm,

${c}^{2} = {5.1}^{2} + {6.3}^{2}$

${c}^{2} = 26.01 + 39.69$

${c}^{2} = 65.7$

$c = \sqrt{65.7}$

$c = 8.106cm \: (3d.p)$

3 = q/11 i need it real quick

makkiz [27]

Answer:

$q=33$

Step-by-step explanation:

So we have:

$3=\frac{q}{11}$

Multiply both sides by 11:

$11(3)=(11)\frac{q}{11}$

The right side cancels:

$11(3)=q$

Multiply the left:

$33=q$

Thus, the value of q is 33.

CAN ANYONE HELP ME ASAP?!? PLEASEEE! I’ll give brainliest! <br> 1-4

liraira [26]

Answer:

35 degrees

42 degrees

x = 8 degrees

x = 7 degrees

Step-by-step explanation:

m <1 = 70/2 = 35 degrees

m <1 = 84/2 = 42 degrees

6 + 4 x = (9 x + 4) / 2

12 + 8 x = 9 x + 4

12 - 4 = x

x = 8 degrees

3 x - 1 = x + 13

2 x = 14

x = 7 degrees
